if the area of a rectangle is width time length, then we have all of the info we need.

the width is 6 less than 3 times the length. let the length be x and put your words into math! 6 less is -6. 3 times a number is 3x, so width=3x-6.

so we have area=l×w which becomes x×(3x-6)=105

solve
x(3x - 6) = 105 \n 3 {x}^(2) - 6x = 105 \n 3( {x}^(2) - 2x) = 105 \n (1)/(3) * 3( {x }^(2) - 2x) = 105 * (1)/(3) \n {x}^(2) - 2x = 35 \n {x}^(2) - 2x - 35 = 0
factor and solve!

you will get one positive and one negative. pick the positive since lengths cannot be negative

A square is cut in half on the diagonal creating two equal triangle. Each triangle has an are of 1.32 square units. What is the side length in unit of the orginial square

Answers

What is the side length in unit of the original square?

Let's start by getting the area of the square.
The area of the square is the sum of the areas of the two triangles, or
2 x 1,32  = 2.64 square units.
Now, all sides of a square are the same length. That is the length we need, let's call that length L.
So, the area of the square is L x L = 2.64 square units, which is the same as the square root of 2.64

If area of the path is 120 square feet then 120 pavers will she need to cover the path

What is Area of Rectangle?

The area of Rectangle is length times of width.

Given that Suzi is designing a path with parallelogram-shaped pavers as shown in the diagram.

The area of the path is 120 square feet.

A parallelogram has a base of 2 feet and height of 0.5 feet.

Area of parallelogram 2×0.5

which is 1 square feet

Now let us find the number of pavers  she need to cover the path

120×1

120

Hence, if area of the path is 120 square feet then 120 pavers will she need to cover the path

100% = 82$
25% = 0,25 = ?

82$ * 0,25 = 20,5$
100% + 25% = 82$ + 20,5$ = 102,5$ whole

................................................................
2way

82$ * (1 + 0,25( = 82$ * 1,25 = 102,5$
You need to multiply $82 by 0.25 (which is 25%). You get $20.50. Just add $82 and $20.50 to get your total cost of the bill. It'll be $102.50
