Maria is putting a border around a right triangle and needs to figure out the triangle's height. If the triangle has a base length of 20 mm and a total area of 100 mm² what is the height?
To find the height of the triangle, we can use the formula for the area of a triangle:
Area = 1/2 * base * height
Given that the base length is 20 mm and the total area is 100 mm², we can plug in these values into the formula:
100 = 1/2 * 20 * height
Simplifying:
100 = 10 * height
10 = height
Therefore, the height of the triangle is 10 mm.
