Question

length of a rectangle is 8m more than its breadth and its perimeter is 128m find its length and breadth

Answer 1

Let breadth be b

Length be l

Given l = b+ 8 

Perimeter = 2(l+b) = 128

l + b = 64

b+8+b = 64

2b = 56

b = 28

l = 8+28 = 36

Answer 2

Hey friend !! here is your answer

______________________________


◆let the length be x & breadth be y

◆ACCORDING TO QUESTION

◆x=8+y------(1)

◆2(x+y)=128

◆x+y=128/2

◆x+y=64-----(2)


◆Put value of x

◆8+y+y=64

◆2y=64-8

◆y=56/2

◆y=28cm

◆x=8+y

◆x=8+28=36cm

---> So length is 36cm & breadth is 28cm
