Question

Picture of question below

Answer 1

99

Explanation:

area of a triangle formula =
`(bh)/(2)`

where b = base length and h = height

The triangle shown has a base length of 11 and a height of 18

Using this information we plug in the values into the formula

`A=(11*18)/(2) \\11*18=198\\(198)/(2) =99`

Hence the area of the triangle is 99ft²
