The lengths of the sides of a triangle are 5 m, 5 m and 8 m. What is the area of the triangle?

$12 m^2$

We have,

The lengths of the sides of a triangle are 5 m, 5 m and 8 m

We can see that this is an isoceles triangle with right angle.

H = 5

B = 4

and P = 3 ( From triplet)

So the area of this triangle will be equal to the Base × Height

= 4 × 3 =  $12 m^2$
