Question

If length of rectangle is 3 × breadth and its perimeter is 88cm then what is its breadth??​

Answer 1

Answer:

According to given condition:-

Breadth - x

length - 3x

▬▬▬▬▬

It's perimeter = 2 × ( l + b)

$\implies$ 88 = 2 × (3x + x )

$\implies$ 88 = 6x + 2x

$\implies$ 88 = 8x

$\implies$ x = $\dfrac{88}{8}$ = $\boxed{\sf{11}}$
