Question

find the area of an isosceles triangle whose equal sides are 15 cm​

Answer 1

Answer:

112.5 cm²

Step-by-step explanation:

You wrote the question a little incomplete,

The triangle should be a right-angled isosceles triangle.

The area will be = 1/2×b×h

Because base and height both are 15 cm

= 1/2 ×15×15 cm²

= 225/2 cm² = 112.5 cm²

Answer 2

Hi! friend.

Answer →

→ Area of triangle = 1/2 × base × height

→ Area of triangle = 1/2 × 15 × 15

→ Area of triangle = 225/2

→ Area of triangle = 112.5cm²

Hence, Answer is 112.5cm².
