Question

area = (15) 7×10=70 (right triangle with legs 7 yd and 10 yd) area =

Explanation:

Step1: Recall the formula for the area of a right triangle.

The area \( A \) of a right triangle is given by \( A = \frac{1}{2} \times \text{base} \times \text{height} \).

Step2: Identify the base and height.

From the diagram, the base is \( 7 \) yd and the height is \( 10 \) yd.

Step3: Substitute the values into the formula.

\( A = \frac{1}{2} \times 7 \times 10 \)

Step4: Calculate the area.

First, multiply \( 7 \) and \( 10 \): \( 7 \times 10 = 70 \). Then, multiply by \( \frac{1}{2} \): \( \frac{1}{2} \times 70 = 35 \).

Answer:

The area of the right triangle is \( 35 \) square yards.
