Question

the length and breadth of a rectangular field are in the ratio 7:4. if the perimeter is 440meter find the length and breadth​

Answer 1

Let the length of the field be 7x and breadth be 4x

Perimeter of the field = 2(l+b)

According to the question,

440 = 2(7x + 4x)

440 = 2(11x)

440 = 22x

x = 440/22

x = 20

Length of the field = 7 x 20

= 140m

Breadth of the field = 4 x 20

= 80m
