Answer 1

To find the area of an equilateral triangle, you can use the formula:

\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]

In this case, the base of the triangle can be taken as one of the sides, which is 10 inches, and the height is given as 7 inches. Plugging in these values:

\[ \text{Area} = \frac{1}{2} \times 10 \times 7 = \frac{1}{2} \times 70 = 35 \text{ square inches} \]

Therefore, the area of the equilateral triangle is:

C) 35 sq. in.
