Question

how to solve this problem ​

Answer 1

Answer:

According to figure

Length = 5y + 4 and

Breadth = 2y + 36

Perimeter of a rectangle = 2(l + b)

It is given that the perimeter is 220

2(l + b) = 220

= l + b = 220/2 = 110

= 5y + 4 + 2y + 36 = 110

7y = 110 - 40

= y = 70/7 = 10

For y = 10 Perimeter of the rectangle is 220 cm
