The equation below shows The area of a trapezoid, a, with a height of 9 cm, and one base 35 cm. A=9/2(b+35)
Which formula correctly solves for the other base, b?
For this case we have the following equation: A = 9/2 (b + 35) We must clear b from the equation, to obtain the value of the other base. Clearing b we have: (b + 35) = (2/9) A b = (2/9) A - 35 Answer: A formula that correctly solves for the other base, b is: b = (2/9) A - 35
