A triangle has a base of 10 cm its other sides are both 13cm long calculate the area

60cm^2

Explanation:

Since both sides are 13cm it tells us that it is an isosceles triangle.

And we can find the height by using Pythagorean’s theorem.

If we cut the isosceles triangle into 2 same right triangles, we can take one of the right triangle and we can work out the height.
