Question

What is the area of triangle with a base of $2\frac{1}{2}$ inches and a height of $2$ inches?

• A. $2\frac{1}{4}in{.}^2$
• B. $2\frac{1}{2}in{.}^2$
• C. $4\frac{1}{2}in{.}^2$
• D. $5in{.}^2$

Answer 1

The correct option is B

$2\frac{1}{2}in{.}^2$

Explanation for correct answer.

We know that area of triangle $=\frac{1}{2}\times base\times height$

$$\begin{gathered} =\frac{1}{2}\times 2\frac{1}{2}\times 2 \\ =2\frac{1}{2}in{.}^2 \end{gathered}$$

Hence, The correct option is B.
