Question

the perimeter of a rectangle paper of breadth 23/2 cm is 30 cm. find the length of the paper ?​

Answer 1

Answer:

Breadth of the rectangular paper, b=1112=232b=1112=232 cm

Let length of the paper =l=l cm

Using formula, Perimeter of the rectangle =2(l+b)=2(l+b)

It is given that perimeter is 3030 cm

So,

2(l+232)=302(l+232)=30

l+232=302=15l+232=302=15

l=15−232l=15−232

l=30−232l=30−232

l=72l=72 cm
