Question

the perimeter of a rectangle is 36 m. Its length is 10 m . what is its breadth?​

Answer 1

• we fill find it like this

$2(l + b)$

$2(10m + b) = 36m$

$10m + b = 36 \div 2$

$10m + b = 18m$

$18m - 10m = 8m$

therefore

BREADTH OF RECTANGLE =8M

LENGTH OF RECTANGLE=10M

We can prove it like this

$2(l + b)$

$2(10 + 8) = 2 \times 18 = 36m$
