20. The perimeter of a square is 72 in. What is its area?
ivanzaharov [21]

The formula for perimeter is length + length + width + width

You know that all the sides of a square are equal to each other. That means that all the values in the perimeter formula should be the same. Therefore you can divide 72 by 4 (perimeter divided by the number of sides)

72 / 4 = 18

^^^Each side is 18 in

The formula for are is...

A = length x width

so...

18 * 18 = 324

324 in^2

Hope this helped!

50 POINTS Really need help, answer a. b. and c.
AleksandrR [38]

Answer:

a) 1 in : 6 in

b)  P=32 inches

    A =60 inches ^2

c) P=  16 ft

    A = 15 ft ^2

Step-by-step explanation:

The drawing is 6 inches tall, while the real flag is 3 ft tall

Change ft to inches

3 ft * 12 inches/1ft = 36 inches

drawing : real life

  6                 36

 Divide each by 6

  1                    6

The scale is 1 to 6

So for every 1 inch on the drawing, there is 6 inches in real life


b)  P= 2(l+w) = 2(10+6) = 2(16) = 32 inches

    A = l*w = 10*6 =60 inches ^2

C)

The drawing is 10 inches by 6 inches

Multiply by the scale factor of 6

Real life is     60 inches by 36 inches

Divide by 12 to get back to ft

                            5ft    by 3 ft

P= 2(l+w) = 2(5+3) = 2(8) = 16 ft

    A = l*w = 5*3 =15 ft ^2
