Question

The length of a rectangle is 10 cm more than its breadth. If the perimeter of rectangle is 80 cm, find the dimensions of the rectangle. *



a 20 cm, 30 cm

b 15 cm, 25 cm

c 14 cm, 24 cm

d 10 cm, 20 cm

​

Answer 1

Answer:

Let the breadth=xcm

length=x+10

Perimeter=80m

2(l+b)=80m

l+b=40

x+10+x=40

x=15cm

then,length=15+10=25

l=25cm

Dimension(l,b)=(25cm,15cm)
