The problem presented above is an example in which we can use the concept of ratio and proportion. The ratio between the heights of Mei and the statue should be the same to the ratio of their shadows. Letting x be the height of the statue.
5 ft/ x ft = 3 ft / 10.5 ft
The value of x from the equation above is 17.5 ft.
The roof is made up of 2 similar pieces of 2 rectangle shapes.
----------------------------------------------------------------
Area of a rectangle = Length x Width
----------------------------------------------------------------
Area of a rectangle = 50 x 14 = 700 ft²
----------------------------------------------------------------
Area of 2 rectangle pieces:
----------------------------------------------------------------
Area of 2 rectangle pieces = 700 x 2 = 1400 ft²
----------------------------------------------------------------
Find the cost:
----------------------------------------------------------------
1ft² = $2.75
1400 ft² = 2.75 x 1400
1400 ft² = $3850
---------------------------------------------------------------------------------------------
Answer: It will cost $3850 to have the roof replaced. (Answer A)
