Question

If the breath is 3 times more than the length and the perimeter is 88 find the area

Answer 1

Answer:

Let length be 'l' and width be 'b'

from the question,

length is 3 times of width so

l=3b..........(1)

also, perimeter is 88 cm

2(l+b)=88

or,2(b+3b)=88 {l=3b from 1}

or,8b=88

∴b=11cm

now for length

l=3b

or l=3*11

∴length=33cm

Step-by-step explanation:
