A. 70 sq. in.
B. 20 sq. in.
C. 44 sq. in.
D. 35 sq. in

Answer 1

your answer is D. Because the area of a triangle is 1/2bh...10 is your base and 7 is your height ...7*10 =70 then divide by 2... the area is 35

Answer 2

Answer: D.
`35\ in^2`

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}=(1)/(2)* base* height\\\\\Rightarrow\ \text{Area}=(1)/(2)*10*7\\\\\Rightarrow\ \text{Area}=35\ in^2`

Hence, the area of the given equilateral triangle =
`35\ in^2`
