Question

the area of the triangle below is 3.63 square inches. what is the length of the base? 2.2 in answer b = in submit answer

Explanation:

Step1: Recall the area formula of a triangle

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

Step2: Rearrange the formula to solve for \(b\)

From \(A = \frac{1}{2}\times b\times h\), we can get \(b=\frac{2A}{h}\).

Step3: Substitute the given values

Given \(A = 3.63\) square inches and \(h=2.2\) inches. Substitute into \(b=\frac{2A}{h}\), we have \(b=\frac{2\times3.63}{2.2}\).
First, calculate \(2\times3.63 = 7.26\). Then, \(b=\frac{7.26}{2.2}=3.3\).

Answer:

\(3.3\)
