Answer 2

Given,

Measures of a triangle - 3cm,3cm and 4cm.

To Find,

The area of the Triangle

Solution,

As per the Heron's formula,

A = $\sqrt{S (S-a) (S-b) (S-c)}$ where a, b and c are 3 sides of the triangle.

Semiperimeter (S) = $\frac{a+b+c}{2}$ = $\frac{3+3+4}{2}$ = 10/2 = 5

Substituting the values,

= $\sqrt{5 (5-3) (5-3) (5-4)}$

= $\sqrt{5 * 2 * 2 * 1}$ ( As there are two 2s we can take one out)

= $2 \sqrt{5}$

Therefore the area of the triangle is $2\sqrt{5}$ cm square or 4.47 cm square.
