Question

The sides of a triangular park are 42m,34m ,24m ,find the cost of turfing the park at rs 15 per sq.m

Answer 1

The area of a triangle when 3 sides are given is
$\sqrt[]{s(s - a)(s - b)(s - c)}$
where s = semi-perimeter = perimeter÷2

s = (42+34+24)/2 = 100/2 = 50m

Area =
$\sqrt[]{50(50 - 42)(50 - 34)(50 - 24)}$

Answer 2

the side of a triangle Park are 42 m 34 m 24 m find the cost of turfing the park at rupees 15 per square metre
