Question

Find the perimetre of reatangle whose area is 500m2 and breathe is 20m

Answer 1

Area =500m2

Breadth=20m

Let length =l

Area of rectangle =length×breadth

Put the values

500=l×20

l=500/20

l=25

Length=25m

Answer 2

Hey ,

Here is your answer,

___________________________________

perimeter of rectangle = 500 m²

breadth of rectangle = 20 m

length of rectangle = x

let us consider the breadth of the rectangle as "x"

perimeter of rectangle = 2 ( l + b )

l b  = 500

x  x 20 = 500

bringing 20 to right hand side ,

20x = 500

x = 500/20

x = 25 m.

the breadth of the rectangle is 25 m .
