Question

here you go the brainless

Answer 1

Area of trapezium
= ½(a + b)h
= ½(15 + 10)(12)
= 150 feet²

Answer 2

Hi there!

The formula for an area A of a trapezoid with height h and bases of b1 and b2
A = h(b1+b2)/2

h= 12
b1 = 10
b2 = 15

A = 12(10+15)/2
= 6 * 25
= 150

The area is 150 ft².
Have an awesome day! :)
