Question

The length of a rectangle is 5 cm more than its breadth. If the perimeter of the rectangle is 50 cm than what is the area.

Answer 1

let breadth be x,length be 5+x

perimeter of rectangle =2(l+b)
50=2(5+x+x)
50=10+2x+2x
50=10+4x
4x=50-10
4x=40
x=40/4=10

therefore,breadth is 10 and length is 15

Answer 2

let the breadth of rectangle is x than length is x+5.

2(L+B)=50
2(x+5+x)=50
10+4x=50
4x=40
x=10

than length is x+5=10+5=15,breadth=x=10

area=l×b
=15×10
=150

tell me I am write or not
