Answer: D. \(35\ in^2\)
Step-by-step explanation:
Given: Side of equilateral triangle = 10 inches
Height of equilateral triangle= 7 inches
We know that the area of triangle is given by :-
\(\text{Area}=\frac{1}{2}\times base\times height\\\\\Rightarrow\ \text{Area}=\frac{1}{2}\times10\times7\\\\\Rightarrow\ \text{Area}=35\ in^2\)
Hence, the area of the given equilateral triangle =\(35\ in^2\)
