Question

the length and breadth of a rectangular field is in the ratio 4 : 3 and its perimeter is 112 M then its area is​

Answer 1

Answer:768m²

Step-by-step explanation:

Let the ratio factor be x then,

length=4x

breadth=3x

perimeter of rectangle= 2(l+b)

112=2(4x+3x)

112=7x

2

56=7x

x=8

∴length= 4(8)= 32m

 breadth= 3(8)= 24m

Area of rectangle= lxb

Area= 32 x 24

Area=768m²
