Question

The triangle has an area of 7 7/8
`cm^(2)` and a base of 5 1/4 cm. What is the length of h? Explain your reasoning.

Answer 1

3 cm

Explanation:

You want the height of a triangle with area 7 7/8 cm² and a base of 5 1/4 cm.

Area

The area formula is ...

A = 1/2bh

Solving for h, we get ...

h = 2A/b

Height

Filling in the given values gives the height as ...

h = 2(7 7/8)/(5 1/4) = (126/8)/(42/8) = 126/42 = 3 . . . . cm

The length of h is 3 cm.
