Question

What is the measure of the base of triangle that has an area of $20$ $i{n}^2$ and whose height measures $2in$?

• A. $12in$
• B. $20.5in$
• C. $20in$
• D. $15in$

Answer 1

The correct option is C $20in$

Area of $\Delta =\frac{1}{2}\times base\times height=20{in}^2$

$\Rightarrow \frac{1}{2}\times base\times 2=20\Rightarrow base=20in$
