Question

The area of a rectangle is 3920 square meters. If the ratio of the length to the width is 5:4, find the perimeter of the rectangle

Answer 1

Answer: 252m

Step-by-step explanation:

The length of the rectangle will be 70m while the width will be 56m. To check if it's applicable to the ratio 5:4, we can divide the numbers by 14.

70 ÷ 14/56 ÷ 14 = 5/4 = 5:4

Perimeter = 2(length + width)

= 2(70 + 56)

= 2 × 126

= 252 meters
