Question

find the area. 18 ft 48 ft $a = ? ft^{2}$

Explanation:

Step1: Recall the area formula for a triangle

The formula for the area of a triangle is \(A=\frac{1}{2}\times base\times height\).

Step2: Identify the base and height

Here, the base \(b = 48\) ft and the height \(h=18\) ft.

Step3: Substitute values into the formula

Substitute \(b = 48\) and \(h = 18\) into \(A=\frac{1}{2}\times b\times h\), we get \(A=\frac{1}{2}\times48\times18\).
First, calculate \(48\times18 = 864\). Then, \(\frac{1}{2}\times864=432\).

Answer:

432
