Question

if the area of the rectangle shown is 150 square feet, we can use the equation 2x squared - 5x = 150 to find its dimensions. if the solution to the equation is x=10, what are the dimensions of the rectangle

Answer 1

factoring the left side of the equation

x(2x-5) = 150

x = 10 so the dimension are 10 and (2(10) - 5 = 15

length = 15 feet , width = 10 feet.
