Question

10. Write an expression in simplified form to represent the area of the trapezoid.

Answer 1

Answer:

48$x^{7}$y

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h (b₁ + b₂ )

where h is the height and b₁, b₂ the parallel bases , then

A = $\frac{1}{2}$ × 4$x^{5}$ × (9x²y + 15x²y )

   = 2$x^{5}$ × 24x²y

   = 48$x^{7}$y
