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
Answer: Length of the base is <span><u>5.5 cm</u></span><u />.
Doublecheck:
1/2 * 5.5 * 8 =
= 2.75 * 8 =
= 22
Correct :)
That equals 1 4/16 or 1 1/4.
(-1,3)
Not sure if it’s right but it should be
X = (7 + Y) (7 - Y)
2 + Y
