Question

A rectangle has dimensions in the ratio 4:3. If its area is 192 m2
Find its length and bread
Hence find its perimeter.​

Answer 1

Answer:

length=16m

breadth= 12m

Perimeter=56m

Step-by-step explanation:

let's consider a common factor as 'x'

ratio = 4:3

therefore, 4x= l

3x= b

area of rectangle= 4x*3x

192 = 12x²

192/12= x²

16 =x²

therefore, x = 4m

since x=4,

length = 4*4= 16m

breadth= 3*4= 12m

perimeter= 2(16 +12)= 56m
