Question

2 - arithmetic reasoning
a triangular piece of art made of fabric will have a base of 12 feet and a height of 8 feet. how many square feet of fabric is needed for the art?
a 24
b 40
c 48
d 96
if d is your answer, click the next button. otherwise, select another answer

Explanation:

Step1: Recall the formula for the area of a triangle

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

Step2: Substitute the given values into the formula

Given \(b = 12\) feet and \(h=8\) feet. Then \(A=\frac{1}{2}\times12\times8\).
First, calculate \(12\times8 = 96\). Then \(\frac{1}{2}\times96=48\).

Answer:

C. 48
