Question

the lenght of a rectangle is 20 cm more than its breadth.if perimeter is 100 cm , find the dimension of the rectangle
​

Answer 1

Answer:

Let the breadth be x.

therefore, length =x+20

p=100cm

2(x+20+x)=100

4x+40=100

4x=100-40

x=60/4

x=15

therefore, breadth=15cm and length =15+20=35cm.
