Question

1. 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. 60 sq m
b. 40 sq m
c. 10 sq m
d. 20 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

Given \(base = 8\) meters and \(height = 5\) meters. Substitute into the formula: \(A=\frac{1}{2}\times8\times5\).

Step3: Calculate the value

First, calculate \(8\times5 = 40\). Then, \(\frac{1}{2}\times40=20\). So the area \(A = 20\) square meters.

Answer:

D. 20 sq m
