Question

answer attempt 1 out of 2
the length of the base is □ and the length of the height is □. therefore the area of
the triangle is \frac{1}{2}\times□\times□=?

Explanation:

Step1: Identify base and height

The base of the triangle is \(5.5 + 6.3=11.8\). The height \(h = 3.88\).

Step2: Calculate the area

The formula for the area of a triangle is \(A=\frac{1}{2}\times b\times h\). Substitute \(b = 11.8\) and \(h = 3.88\) into the formula: \(A=\frac{1}{2}\times11.8\times3.88\).

First, calculate \(11.8\times3.88 = 11.8\times(4 - 0.12)=11.8\times4-11.8\times0.12=47.2-1.416 = 45.784\).

Then, \(\frac{1}{2}\times45.784 = 22.892\).

Answer:

The length of the base is \(11.8\) and the length of the height is \(3.88\). Therefore the area of the triangle is \(\frac{1}{2}\times11.8\times3.88 = 22.892\).
