Question

A rectangle has perimeter of 40m.If the rectangle has a breadth which is 4 m
less than its length, then what are its dimensions?​

Answer 1

Step-by-step explanation:

Let the length be x

then, breadth = x-4

atq,

2(x+x-4)=40

2(2x-4)=40

2x-4=40/2=20

2x=20+4=24

x=24/2=12

length, x= 12

breadth x-4=12-4=8

Answer 2

$\huge{\boxed{\mathtt{\purple{Answer}}}}$

Let the length be x
then, breadth = x-4
atq,
2(x+x-4)=40
2(2x-4)=40
2x-4=40/2=20
2x=20+4=24
x=24/2=12
length, x= 12
breadth x-4=12-4=8
