Final answer:
The area of the window is 14 square feet.
Step-by-step explanation:
The area of a trapezoid with bases b1and b2 and height ℎ is 1/2(b1 + b2)h.
To find the area of Eliana's stained-glass window, we can use this formula. The height of the window is 4 feet and the bases are 3 feet and 4 feet. Plugging in these values into the formula, we have: Area = 1/2(3 + 4) * 4 = 1/2(7) * 4 = 7 * 2 =
14 square feet.
