question ⚫⚫⚫

The perimeter of a rectangle is 40m its length is 4 time it's breadth . Find area of rectangle.


solution ⚫⚫

perimeter =40 m

let the breadth be X

so the length is 4 x

according to question
2 x (2x+x)=40

2×5x=40

10x=40

x=40/10=4

so
the breadth is 4 m

and the length is
4×4=16 m


area = length X breadth = 64 m^2
$4 \times 16 = 64$

Area of rectangle will be 64
