Question

Two rectangle are congruent to each other. If length of the first rectangle 12.5cm and perimeter of the second rectangle is 34cm, then breadth of the second rectangle is

Answer 1

A.T.Q.,Let breadth be x and x
12.5+12.5+x+x=34
25+2x=34
2x=34-25
2x=9
x=9/2
x=4.5

Answer 2

Given that 2 rectangles are congruent so corresponding sides are equal
Given length=12.5cm
perimeter=2(length+bredth)
34=2(12.5+b)
34=25+2b
34-25=2b
9=2b
9/2=b
bredth=4.5cm
