Question

Length of a rectangle is 3 times its width if the perimeter is 88 cm then find the length and breadth of rectangle

Answer 1

Answer:length=33cm and width=11cm

Step-by-step explanation:

here

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

Answer 2

Let length and breadth be l and b

l=3b (given)

2(l+b)=88 (given)

l+b=44

3b+b=44

b=11

a=3b

=3×11

=33
