Bobby is designing a garden in the shape of a trapezoid that is split into three parts: two triangular flower beds, and a rectangular section of grass. Setting up the flower beds costs $4.25 per square foot. How much will Bobby have to spend to set up the flower beds?

since the 2 triangle sides are equal just add them up to be another rectangle, and since we need volume just multiply the numbers and add, 11.75*12 and 11*9 which are 141 and 99 and when added becomes 240, to find the cost multiply by the 4.25 to get $1020

The answer is $449.44.
