Question

The Length of a rectagle is 5cm more than its breadth If the permeter of a rectangle is 70cm.find its length and breadth?

Answer 1

Step-by-step explanation:

Let breadth be x then,

length = x+5

perimeter= 70 cm

We know that perimeter of rectangle = 2(l+b)

2(x+5+x)=70

2(2x+5)=70

4x+10-70=0

4x-60=0

4x=60

x=60/4

x=30/2

x=15

so, breadth = 15 and length = x+5. 15+5=20

breadth=15 cm , length=20 cm
