Can anybody help me out with this question? (Area)
oksano4ka [1.4K]

Answer: 788.48 feet squared.

Step-by-step explanation:

First, bring the rectangle to its true size. You can do this by multiplying each side by the ratio 8ft/5cm. This is to remove centimetres from the equation.

22 * 8 / 5 = 35.2 feet

14 * 8 / 5 = 22.4 feet

Next, you can multiply the two sides together to get your area, which is 788.48 feet squared.
