Area of a triangle two sides of which are 18 cm and 12 cm

and the perimeter is 44 cm.

≈ 83.9 cm²

Step-by-step explanation:

Given:

Then:

Area of  the triangle is found by using Herons formula:

where s = P/2 = 44/2 = 22 cm

Step-by-step explanation:

Two sides of the triangle are given.

The perimeter is given.

We need to solve for the third side.

The measure of the third side is 14 cm.

When three sides of the triangle are given, we can solve for the area using Heron’s formula.

Plugging in the values and evaluating.

The area of the triangle is approximately 83.9 cm².
