Question

The triangle has an area of 7-7/8 cm² and a base of 5-1/4 cm. What is the length of h? Explain your reasoning.

Answer 1

3

Explanation:

The equation for the area of a triangle is A=1/2(b)(h)

we have the area and the base, so we plug those values in resulting in 7 7/8=1/2(5 1/4)(h)

From there, we solve. Multiply 5 1/4 by 0.5, resulting in 2.625

then, you divide 7 7/8 by 2.625 and you get 3.
