Question

a designer plans to create a triangular garden area with a base of 8 meters and a height of 5 meters. what is the area of the garden?
a. 20 sq m
b. 40 sq m
c. 60 sq m
d. 10 sq m

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: Substitute the given values into the formula

Here, the base \(b = 8\) meters and the height \(h=5\) meters. So, \(A=\frac{1}{2}\times8\times5\).
First, calculate \(8\times5 = 40\). Then, \(\frac{1}{2}\times40=20\).

Answer:

A. 20 sq m
