A:

Answer:280 ft squaredStep-by-step explanation:To find the area of the nonshaded portion, we can find the area of the entire floor and then subtract the shaded area.The total area is that of a rectangle: 30 * 15 = 450 ft squared.Now, the shaded region is made up of a rectangle and a triangle.- The rectangle has length 8 and width 10, so its area is 10 * 8 = 80 ft squared.- The triangle has base 12 and height 15, so using the area of a triangle formula: [tex]A=(bh)/2[/tex] (where b is the base and h is the height) = (12 * 15)/2 = 180/2 = 90 ft squared.- The total shaded region is: 80 + 90 = 170 ft squaredSubtract 110 from 450: 450 - 170 = 280 ft squared.Thus, the answer is 280 ft squared.Hope this helps!
