Question

15in, 40in, 50in (right triangle with right angle), area: ______

Explanation:

Step1: Identify triangle type

It's a right - triangle, so legs are base and height. Here, base = 40 in, height = 15 in.

Step2: Use area formula for triangle

The formula for the area of a triangle is $A=\frac{1}{2}\times base\times height$. Substitute base = 40 and height = 15 into the formula: $A = \frac{1}{2}\times40\times15$.

Step3: Calculate the area

First, calculate $40\times15 = 600$. Then, $\frac{1}{2}\times600=300$.

Answer:

300 square inches
