Question

Perimeter of isosceles triangle is 42cm and its base is 3upon 2 times each of equal side of it
is isoscleas triangle find perimeter.

Answer 1

Step-by-step explanation:

Let the equal side of the isosceles triangle be x Base of isosceles triangle = (3x/2) Given perimeter of isosceles triangle = 42 cm That is (x + x +3x/2) = 42 7x / 2 = 42 Therefore x = 12 cm The equal sides are 12 cm each. Base is 18 cm Using heron's formula find the area of the required
