Question

using a formula to find the area of a triangle
find the area of the triangle.
the area of the triangle is square units.
8 units
10 units

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

From the figure, the base \(b = 10\) units and the height \(h=8\) units.

Step3: Substitute the values into the formula

Substitute \(b = 10\) and \(h = 8\) into \(A=\frac{1}{2}\times b\times h\). So \(A=\frac{1}{2}\times10\times8\).
First, calculate \(10\times8 = 80\). Then, \(\frac{1}{2}\times80=40\).

Answer:

40
