The formula for the area of a triangle is A=12bh , where b is the base of the triangle and h is the height of the triangle. What
is the length of the base if the area is 22 cm2 and the height is 8 cm?
2 answers:
If the formula is A = 1/2 * b * h and we know that A = 22 and h = 8, then we can write it down as:
22 = 1/2 * b * 8
22 = 1/2 * 8b
22 = 4b / ÷ 4 (both sides)
b = 5.5

Doublecheck:
1/2 * 5.5 * 8 =
= 2.75 * 8 =
= 22
