The formula for the area of a triangle is a=1/2bh, in which b represents the length of the bass h represents the height. if a triangle has an area of 192 mm2 and height is 12mm what is the measure of the base?

A = 1/2 bh
192 mm^2 = 1/2 b 12
192 = b 6
192/6 = b
32 = b
.
Therefore, the height of the base is 32 mm

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
