A gardening box has a perimeter of 27 1/2 feet. if the length is 9 feet, what is the area?

Answers

Answer 1

Answer:

42 ³/₄ ft²

Further explanation

Given:

A gardening box has a perimeter of 27 ¹/₂ feet.
The length is 9 feet.

Question:

What is the area?

The Process:

A gardening box is rectangular. Units of length that are the same, i.e., in feet.

The perimeter formula is as follows:

$\boxed{ \ Perimeter = length + length + width + width \ }$

It can also be written as follows:

$\boxed{\boxed{ \ Perimeter = 2 * (length + width) \ }}$

Step-1: calculate the width

Let's use the formula above.

$\boxed{ \ 2 * (9 + width) = 27(1)/(2) \ }$

$\boxed{ \ 9 + width = (55)/(2) / 2 \ }$

$\boxed{ \ 9 + width = (55)/(2) * (1)/(2) \ }$

$\boxed{ \ 9 + width = (55)/(4) \ }$

$\boxed{ \ width = (55)/(4) - 9 \ }$

$\boxed{ \ width = (55)/(4) - (36)/(4) \ }$

$\boxed{\boxed{ \ width = (19)/(4) \ ft\ }}$

Step-2: calculate the area

The area formula is as follows:

$\boxed{\boxed{ \ Area = length * width \ }}$

$\boxed{ \ Area = 9 * (19)/(4) \ }$

$\boxed{ \ Area = (171)/(4) = 42(3)/(4) \ }$

Thus, the area of a gardening box is $\boxed{\boxed{ \ 42(3)/(4) \ ft^2 \ }}$

Keywords: a gardening box, has a perimeter, 27 1/2 feet, the length, width, 9 feet, what is the area?, rectangular, formula

Answer 2

Answer: To figure out the width is easy all you do is subtract the length twice, because of there being 2 sides that have the same length,and then divide whatever is left. So its 27.5-18=9.5. 9.5/2=4.75. 4.5 is your width. and now area. area=length times width, so a= 9 times 4,75, which is 42.75.

A. 24/6 x 10

B. 24/10 x 6

C. 6/10 x 24

D. 6/24 x 10

Answer:

6/24×6

Answer: The expression shows to find the cost of 10 bottles of water is given by

\dfrac{6}{24}\times 10

×10

Step-by-step explanation:

Since we have given that

Cost of 24 bottles of water = $6

Using " Unitary Method":

Cost of 1 bottle of water is given by

\dfrac{6}{24}=\dfrac{1}{4}

Cost of 10 bottles of water is given by

\begin{lgathered}\dfrac{1}{4}\times 10\\\\=\dfrac{5}{2}\end{lgathered}

×10

Hence, The expression shows to find the cost of 10 bottles of water is given by

\dfrac{6}{24}\times 10

What is Unit of Measurement?

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

We need to find among the given options which are greater than 2 gallons

We know that 1 gallon = 4 quarts, 1 gallon = 8 pints and 1 gallon = 16 cups

A. 5 quarts 2 pints

5/4 gallons + 5/8 gallons

= 1.875 gal

1.875<2

B. 1 gallon 3 quarts

= 1 gallon + 3/4 gallon

= 1.75 gallon

1.75<2

C. 9 quarts

= 9/4 gallons

= 2.25 gal

2.25>2

D. 40 cups

= 40/16 gallon

= 2.5 gallon

2.5>2

E. 1 gallon 9 pints

= 1 gallon + 9/8 gallon

= 2.125 gallon

2.125>2

Hence, 9 quarts, 40 cups and 1 gallon , 9 pints are greater than 2 gallons

She plans to seat 8 people at the dining room table. She will put the rest at round tables with 4 people at each table. What is the fewest number of round tables that Kathleen needs so that each guest will have a seat? Choose all answers that are correct. A. Draw a diagram. Eight people at 1 table, 4 people at round table, 4 people at round table, 4 people at round table, 4 people at round table, 4 people ANNAJACKSON 2 minutes ago AnnaJackson B. Use logical reasoning. Start with 28 people, subtract 8 people who will sit at the dining room table, that leaves 20 people. Keep subtracting 4 people until you get to 0. Count how many times you subtracted 4 people. C. Translate into an equation. 28 – 8 + 4 + 4 = t D. Work backward. There are 28 people coming to the party. There is one dining table, so subtract 1. Now figure out how many round tables there are and subtract that number.
