Use your equation to find the base of a triangle with an area of 48in^2 and a height of 8 inches
Test please help!
Part A: To solve for b in the formula A = 1/2bh, we need to isolate b on one side of the equation.
1. Start by multiplying both sides of the equation by 2 to eliminate the fraction:
2 * A = 2 * (1/2bh)
2A = bh
2. Divide both sides of the equation by h:
(2A) / h = (bh) / h
2A / h = b
So, the formula for b is b = 2A / h.
Part B: We are given the area (A = 48 in^2) and the height (h = 8 inches), and we want to find the base (b).
1. Substitute the given values into the formula:
b = 2A / h
b = 2 * 48 in^2 / 8 inches
2. Perform the calculations:
b = 96 in^2 / 8 inches
b = 12 inches
Therefore, the base of the triangle with an area of 48 in^2 and a height of 8 inches is 12 inches.
really?
b = 2*48/8 = 12
A = 1/2 bh
2A = bh
b = 2A/h
now use your numbers
