Question

The length and beadth of a rectangle are in the ratio 3:2 if it's perimeter is 30 CM, find it's dimension

Answer 1

Answer:

Lenghth = 9 cm

Breadth = 6 cm

Step-by-step explanation:

Let the length and breadth be 3x and 2x

Perimeter of rectangle = 2×(l+b)

30 = 2×(3x+2x)

3x+2x = 30 / 2 = 15

5x = 15

x = 15 / 5

x = 3

Hence ,

Length = 3x = 3×3 = 9cm

Breadth = 2x = 2×3 = 6 cm
