Number 25 someone help me

Fittoniya [83]

The area of a triangle is given by the formula $A= \frac{1}{2}Bh$ , where B is the base and h is the height. We can rearrange this formula to solve for B.

$\dfrac{A}{ \frac{1}{2}h} = B\\ \\\\\dfrac{2A}{h} = B$ .

We plug in the given area, 640 square millimeters, and the given height, 32 millimeters.

$B= \dfrac{2(640)\ mm^2}{32 \ mm} = 40 \ mm$ .

40 mm is our final answer.
