Benin is sawing boards to make a desk. What is the area of the deck?

108.5 ft²

Step-by-step explanation:

The area of the deck is composite of 3 parts: a right ∆, a rectangle and a ∆.

The area of the deck can be determined by calculating the area of each part as shown below.

Area of the right triangle:

Area = ½*base*height

Base = 6 ft

Height = 7 ft

Area = ½*6*7 = 3*7 = 21 ft²

Area of the rectangle:

Area = length * width

Length = 10 ft

Width = 7 ft

Area = 10*7 = 70 ft²

Area of the other traingle:

Area = ½*base*height

Base = 7 ft

Height = 5 ft

Area = ½*7*5

Area = 3.5*5 = 17.5 ft²

Area of the deck = 21 + 70 + 17.5 = 108.5 ft²

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
