Question

The length and breadth of a rectangular park are in the ratio 4:3 and its perimeter is 56 m. The area of the field is

Answer 1

Step-by-step explanation:

let the length and breadth be 4x and 3x respectively.

perimeter = 2(l+b)

56 = 2(4x+3x)

or, 56/2 = 7x

or, 28 = 7x

or,X = 28/7

or,X= 4

length of rectangle is 4*4 = 16 m

breadth of rectangle is 3*4= 12 m

Area = l*b = 16*12= 192square meter (Ans)
