Question

Number 25 someone help me

Answer 1

The area of a triangle is given by the formula
`A= (1)/(2)Bh`, where B is the base and h is the height. We can rearrange this formula to solve for B.


`(A)/( (1)/(2)h) = B\\ \\\\(2A)/(h) = B`.

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


`B= (2(640)\ mm^2)/(32 \ mm) = 40 \ mm`.

40 mm is our final answer.
