Question

the length of rectangle is 10 metre more than its breadth if the perimeter of the rectangle is 80 metre find the dimensions of the rectangle

Answer 1

if it helpful plzz mark as brainlist and follow me

Answer 2

let the breadth be x
then length be x+10
perimeter=80m
A/q
2 (l+b)=p
2(x+10+x)=80
2x+10=40
2x=30
x=15

so breadth=15m
length=15+10
=25m
