Question

find the area. 42 cm 16 cm a = ? cm²

Explanation:

Step1: Recall the formula for the area of 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 \(b = 42\space cm\) and the height \(h=16\space cm\).

Step3: Substitute the values into the formula

Substitute \(b = 42\) and \(h = 16\) into \(A=\frac{1}{2}\times b\times h\).
