Question

A piece of paper is in the
shape of a right triangle. The
base is 4.25 inches and the
height is 11 inches. What is
the area of the right triangle in
square inches? Express your
answer as a decimal. Do not
round your answer.

Answer 1

To find the area of a right triangle, you can use the formula:

\[
\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}
\]

In this case, the base is 4.25 inches and the height is 11 inches. Plugging in these values into the formula gives:

\[
\text{Area} = \frac{1}{2} \times 4.25 \times 11
\]

Calculating it step-by-step:

1. Calculate \(4.25 \times 11\):
\[
4.25 \times 11 = 46.75
\]

2. Now multiply by \(\frac{1}{2}\):
\[
\text{Area} = \frac{1}{2} \times 46.75 = 23.375
\]

So, the area of the right triangle is

\[
\boxed{23.375} \text{ square inches.}
\]
