Question

Sides of a triangle are in the ratio 5:3:3.Perimeter of a triangle is 110 cm.Find the area of the triangle

Answer 1

$\sf\underline{Step-by-step \: explanation}$

Let the numbers be, 5x, 3x and 3x.

Acc. to the question,

5x + 3x + 3x = 110

11x = 110

x = 10 (110 ÷ 11)

5x = 5×10 = 50 cm

3x = 3×10 = 30 cm

3x = 3×10 = 30 cm

_______________________________

Area = h×b/2

Area = 5×3/2

Area = 7.5 cm^2
