mary has 39 square feet of patio bricks. each square brick has sides 1 foot long. what is the greatest perimeter of a rectangle that she can make with bricks

Answers

-- The smallest perimeter you can make with a certain area
is a circle.

-- The NEXT smallest perimeter with the same area is a square.

   With 1-ft by 1-ft square bricks, the shortest perimeter she could
make would be by using her bricks to make it as square as possible.
Without cutting bricks into pieces, the best she could do would be

       (13 bricks) x (3 bricks) .

= (13-ft) x (3-ft)

   Perimeter = (2 x length) + (2 x width)

   = (2 x 13-ft) + (2 x 3-ft)

   =      (26-ft) + (6-ft) = 32 feet <== shortest perimeter.

-- Then, the more UNSQUARE you make it, the more perimeter
it takes to enclose the same area. That means Mary has to make
a rectangle as long and skinny as she can.

The longest perimeter she can make (without cutting bricks into
pieces) is (39 bricks) x (1 brick) .

      = (39-ft) x (1-ft) .

Perimeter = (2 x length) + (2 x width)

   = (2 x 39-ft) + (2 x 1-ft)

   =    (78-ft) + (2-ft) = 80 feet .

What she'll have then is a brick path, 39 feet long and 1 foot wide,
and when you walk on it, you'll need to try hard to avoid falling off
because it's only 1 foot wide.

The largest perimeter possible is 80ft.

What is the greatest perimeter that can be made?

The greatest perimeter is obtained when we put all the bricks on a single line. That is because in this case, we do not have internal bricks that do not apport to the perimeter.

In that case, we would get a rectangle that measures 39 ft by 1ft, then the perimeter is:

P = 2*(1ft + 39ft) = 80ft

The largest perimeter possible is 80ft.

a scale drawing of a rectangular park is 5 inches wide and 7 inches long. the actual park is 280 yards long. whats the area of the actual park, in square yards?

Answers

The actual area of the park in square yards from the given scale is;

Actual area of park = 56000 yds²

We are told that;

There is a scale drawing of a rectangular park with dimensions;

Width = 5 inches

Length = 7 inches

Now, we are told that the Actual length of the park is 280 yards.

Since the length on the scale drawing is 7 inches, then it means that;

7 inches represents 280 yards

Thus, 1 inch will represent; 280/7 = 40 yards

Thus, actual width = 5 × 40

Actual width = 200 yards

Formula for area of rectangle is;

Area of rectangle = Length × width

Thus;

Actual area of rectangle = actual length × actual width

Actual area of rectangle = 280 × 200

Actual area of rectangle = 56000 yds²

Answer:

Area of the actual park is 56000 square yards.

Step-by-step explanation:

A scale drawing of a rectangular park has dimensions as 5 inches width and 7 inches length.

Actual length of the park has been given as 280 yards.

So scale factor used in the drawing is 7 inches = 280 yards

Or 1 inch = 40 yards

Since width of the rectangular park is = 5 inch

So actual width of the park will be = 5×40 = 200 yards

Now we can calculate the area of the park.

Actual area of the park = Length × Width

= 280×200

= 56000 yards²

Therefore, area of the actual park is 56000 square yards.
