Question

Which expression represents the area of triangle ABC in square meters?

Triangle A B C has a base of 57 meters and a height of 14 meters.
One-half times 14 times 57
One-half times 14 times 64
One-half times 24 times 40
One-half times 24 times 57

Answer 1

The formula for the area \( A \) of a triangle is given by:

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

In your case, the base of triangle ABC is 57 meters and the height is 14 meters. Plugging in these values, we have:

\[
A = \frac{1}{2} \times 57 \times 14
\]

Therefore, the expression that represents the area of triangle ABC in square meters is:

\[
\frac{1}{2} \times 14 \times 57
\]

So, the correct choice is **One-half times 14 times 57**.
