Question

A=1/2 BH where A: area, B: base, & H: height. If the Base of a triangle is 7 ft and the Height of the triangle is 4 ft, what is the Area of the triangle? Question 12 options: 56 ft 28 ft 14 ft 37 ft

Answer 1

`\boxed {\tt A= 14 \ ft^2}`

Explanation:

The area of a triangle can be found using the following formula.

`A=(1)/(2) bh`

where
`b` is the base and
`h` is the height.

In this triangle, the base is 7 feet and the height is 4 feet.

`b= 7 \ ft\\h= 4 \ ft`

Substitute the values into the formula.

`A=(1)/(2) bh`

`A=(1)/(2) (7\ ft)(4 ft)`

Multiply 7 ft and 4 ft.

`A=(1)/(2) (28 \ ft^2)`

Multiply 28 square feet by 1/2 or divide 28 square feet by 2.

`A= 14 \ ft^2`

The area of the triangle is 14 square feet.
