Question

A triangular tent door has an area of 15 square feet. The height is five feet. What is the base?

Answer 1

The base is 6 feet long.,

Explanation:

Area of a triangle = 1/2 * base * height so we have

1/2 b h = 15

1/2 b * 5 = 15

2.5 b = 14

b = 15/2.5

b = 6 feet.

Answer 2

Base = 6 feet

Explanation:

Area of Triangle =
`(1)/(2) Base*Height`

For finding Base:

Base =
`(2(Area))/(Height)`

Where Area = 15, Height = 5

Base =
`(2(15))/(5)`

Base = 2*3

Base = 6 feet
