The length of each equal side of an isosceles triangle is 15 cm and the included angle between those two sides is 90°.Find the area of the triangle.
Answer & explanation
Correct answer: option 4
We have,
Length of each side equal side of an isosceles triangle = 15 cm
If the triangle is an isosceles right-angled triangle, then
Area of the triangle = \(\frac{1}{2}\) × 15 × 15 = \(\frac{225}{2}\)
