Question

The breadth of a rectangle is 1/3 of its length. If the area of the rectangle is 48 cm. Find the length and breadth.

Answer 1

Answer:

length = 12 cm

Breadth = 4 cm

Step-by-step explanation:

Let length = l

breadth = $\frac{1}{3}l$

Area of rectangle = 48 sq.cm

length * breadth = 48

$l * \frac{1}{3}l = 48$

  $\frac{1}{3}l^{2}=48$

    $l^{2}=48*3\\\\l^{2}=144\\\\ l = \sqrt{144}$

   l = 12 cm

breadth =   $\frac{1}{3}l = \frac{1}{3}*12 = 4 cm$

length = 12 cm

Breadth = 4 cm
