A rectangle and a square have the same area equal to 3600 sq cm one side of the rectangle

A rectangle and a square have the same area equal to 3600 sq cm one side of the rectangle is 90 cm which figure has a larger perimeter

Brief entry:

area of figures – 3600 cm ^ 2,

the length of the rectangle is 90 cm,

differential comparison of perimeters.

1. Calculate the width of the rectangle:

3600: 90 = 40 cm.

2. Calculate the perimeter of the rectangle:

(90 + 40) 2 = 260 cm.

3. Determine the side of the square:

v3600 = 60 cm.

4. The perimeter of the square is:

60 4 = 240 cm.

5. Let’s compare the perimeters of the figures:

260 cm – 240 = 20 cm.

Answer: The perimeter of the rectangle is 20 centimeters larger than the perimeter of the square.
