Question

The perimeter of a rectangular sheets is $100cm$. If the length is $35cm$, find the breadth. Also find the area.

Answer 1

Perimeter of rectangular sheet $=100cm$

Length of sheet $\left(l\right)=35cm$

Breadth of sheet $\left(b\right)=?$

As we know that,

Perimeter of rectangle $=2(l+b)$

$\therefore 2(35+b)=100$

$\Rightarrow 35+b=\frac{100}{2}$

$\Rightarrow b=50-35=15cm$

Now,

Area of sheet $=l\times b$

$=35\times 15$

$=525{cm}^2$
