Find the area of the triangle that has a base of 4.2 mm and a height of 1.5 mm. 2.85 mm2 6.3 mm2 3.15 mm2 5.7 mm2
Advocard [28]

Answer: 3.15 mm²

Step-by-step explanation:

First, we multiply the height by the base: 4.2 x 1.5 = 6.3

But, since this is a triangle, we have to divide this number by 2: 6.3 / 2 = 3.15

Hope this helps you!
