Humber/Ontario Real Estate Course 3 Exam Practice

Calculate the total square footage: (a) a 13-foot square room, (b) a trapezoid room with 26 and 31-foot parallel sides, 16 feet apart, (c) a 21x22-foot rectangular room.

1. 1,087 square feet

2. 1,543 square feet

3. 668 square feet

4. 859 square feet

5. 1,312 square feet

6. 1,455 square feet

The correct answer is: 1,087 square feet

To find the total square footage of the rooms described, we calculate the area of each room type and then sum those areas. 1. For the 13-foot square room, the area is calculated by squaring the length of one side. Thus, Area = side × side = 13 ft × 13 ft = 169 square feet. 2. For the trapezoid room with 26-foot and 31-foot parallel sides that are 16 feet apart, the area can be determined using the formula for the area of a trapezoid: Area = (Base1 + Base2) × Height / 2 Area = (26 ft + 31 ft) × 16 ft / 2 = 57 ft × 16 ft / 2 = 456 square feet. 3. For the rectangular room measuring 21 feet by 22 feet, the area is calculated by multiplying the two dimensions: Area = length × width = 21 ft × 22 ft = 462 square feet. Now, summing all the areas gives: - Square room: 169 square feet - Trapezoid room: 456 square feet - Rectangular room: 462 square feet Total square
