Question

find the area. 10 ft 18 ft a =? ft²

Explanation:

Step1: Recall area formula

The formula for the area of a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Identify base and height

Here, $b = 18$ ft and $h=10$ ft.

Step3: Substitute values

$A=\frac{1}{2}\times18\times10$.

Step4: Calculate

$A = 9\times10=90$ ft².

Answer:

90 ft²
