Question

An isosceles triangle has perimeter 50 cm and each of the equal sides is 15 cm. Find the area

of the triangle​

Answer 1

Area of an Isoceles Triangle = 1/2 × a× a =1/2 × a^2

Area of an Isoceles Triangle = 1/2 × a× a =1/2 × a^2 = 1/2 × 15 × 15 = 1/2 × (15)^2

Area of an Isoceles Triangle = 1/2 × a× a =1/2 × a^2 = 1/2 × 15 × 15 = 1/2 × (15)^2 = 1/2 × 225 = 225/2 = 112.5 cm
