Question

The area of a property is 2.2×105 square feet. A house that is on the property has an area of 1600 square feet. How many times greater is the area of the property than the area of the house? Write your answer in standard form.

Answer 1

Area of the property = 2.2 x 10⁵ = 220 000 ft²

Area of the house = 1600 ft²

Number of times the property is greater than the house = 220 000 ÷ 1600 
Number of times the property is greater than the house = 137.5 
Number of times the property is greater than the house = 1.38 x 10²
