Question

what is the area, in square inches, of the shape below?

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: Identify the base and height

Here, the base \(b = 7.6\) inches and the height \(h=5.1\) inches.

Step3: Substitute the values into the formula

Step4: Calculate the product

\(3.8\times5.1=(4 - 0.2)\times5.1=4\times5.1-0.2\times5.1 = 20.4-1.02=19.38\)

Answer:

\(19.38\) square inches
