Practice Set 15.4 Solution (Page No. 101)

(1) Sides of a triangle are cm 45 cm, 39 cm and 42 cm, find its area.

Solution: Area of a Triangle = 1/2 x base x height

Semiperimeter (S) = 1/2 (a + b + c)

Area of a triangle = √s(s-a)(s-b)(s-c)

This formula is known as Heron’s formula.

Sides of the triangle, a = 45 cm, b = 39 cm, c = 42 cm

∴ Semi perimeter (S) = 45 + 39 + 42/2

= 63 cm.

∴ Area = √s(s-a)(s-b)(s-c)

= √63(63-45)(63-39)(63-42)

= √63x18x24x21

= 756 Sq Cm Ans.
