Question

The side of a rectangular plot are in ratio 5:4 and its area is equal to 500sq. M find its perimeter

Answer 1

Answer:

90

Step-by-step explanation:

let length be 5x

then, breadthwill be 4x

5x×4x=500

20x^2=500

x^2=25

x=5

So,length is 5×5=25

Breadth is 4×5=20

Perimeter=2l+2b

perimeter=50+40

Perimeter=90m

Hope you might understand it clearly
