Question

The base of an isosceles right triangle is 30 cm. What is its area?

Answer 1

Answer:

A = 450 cm²

Step-by-step explanation:

Since the right triangle is isosceles then the 2 logs are congruent , both 30 cm and at right angles to each other.

The area (A ) of the triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Here b = h = 30 , then

A = $\frac{1}{2}$ × 30 × 30 = $\frac{1}{2}$ × 900 = 450 cm²
