Question

The sides of a triangle are 60m 100m 140m find the area

Answer 1

Given,

The lengths of the three sides of the triangle = 60 metres, 100 metres and 140 metres.

To find,

The area of the given triangle.

Solution,

We can easily solve this mathematical problem by using the Heron's formula. In this formula, we will use the semiperimeter of the given triangle.

Let us, calculate the semiperimeter of the given triangle,

Semiperimeter (s) = (60+100+140)/2 = 150 metres

Area = ✓150 × (150-60) × (150-100) × (150-140) = ✓150 × 90 × 50 × 10 = ✓6750000 = 2598.07 m²

Hence, the area of the triangle is 2598.07 m².
