Find the area of the isosceles triangle.
13 cm
10 cm

Area of the triangle = 60 cm²

Step-by-step explanation:

Two equal sides of the given isosceles triangle measure 13 cm.

Third side of the triangle = 10 cm

Since, formula to get the area of a triangle with given three sides is given by,

Area =

Where a, b and c represent the sides of the triangle

And s =

For the given isosceles triangle,

s =

s = 18

(s - a) = (18 - 13) = 5 cm

(s - b) = (18 - 10) = 8 cm

(s - c) = (18 - 13) = 5 cm

Substituting these values in the formula,

Area of the triangle =

                                 =

                                 = 60 cm²

Therefore, area of the given isosceles triangle is 60 square cm.
