Question

the ratio ofnthe adjacent side of a rectangle are in the ratio of 2:3perimeter is 125cm find the length of breadth of rectangle

Answer 1

Solution!!

The ratio of the adjacent sides of a rectangle and the perimeter is given in the question.

Ratio = 2:3

Perimeter = 125 cm

Don't get confused. The adjacent sides are nothing else but the length and breadth of the rectangle.

So let the length be 2x and breadth be 3x, respectively.

Perimeter = 2(Length + Breadth)

125 cm = 2(2x + 3x)

125 cm = 2(5x)

125 cm = 10x

x = 125 cm ÷ 10

x = 12.5 cm

Length = 2x = 2 × 12.5 cm = 25 cm

Breadth = 3x = 3 × 12.5 cm = 37.5 cm
