Question

The length of a rectangle is $5cm$ more than the breadth. If the perimeter of the rectangle is $50cm$, find the length and breadth.

Answer 1

We have,

Breadth$=x$

Length$=x+5$

Perimeter$=2(x+x+5)$

$\therefore 50=2(2x+5)$

$\frac{50}{2}=2x+5$

$25=2x+5$

$2x=25-5$

$2x=20$

$x=\frac{20}{2}$

$x=10$

$\therefore$ Breadth$=10$

Length$=x+5$

$=10+5$

$=15$

Hence, this is answer.
