Question

the length of a rectangle is 10m more than its breadth.if the perimeter of the rectangle is 80m , find its dimensions​

Answer 1

Answer:

let the rectangle length be 10x.

let the breadth be x

perimeter of rectangle is 80m

A.T.Q

perimeter of rectangle is 2( l+ b)

2 (10x+x)=80

2×11x=80

22x=80

x=80/22

3.63

so breadth is 3.63 and length is 3.63×10 =36.3

Answer 2

given

length of rectangle=xm+10m

breadth of rectangle=xm

perimeter of rectangle =80m

perimeter of rectangle=2(l+b)

2(x+x+10)=80

2x+10=80/2

2x+10=40

2x=40-10

2x=30

x=30/2

x=15

length of rectangle=x+10

=15+10

=25

breadth of rectangle=x=15
