Question

The sail on a boat is triangular and its area is 216 feet. If the length of the base of the sail is 18 feet, find its
height.

Answer 1

Answer:

24

Step-by-step explanation:

Use the triangle area formula: A=1/2 (base)(height)

Plug in what we know: 216=1/2(18)(h)

Solve for h: (1/2)(18)=9.

216/9=24.

So, h=24

To check, plug it into the formula: 1/2(18)(24)= 216
