Davis used a drawing and a scale factor of 4 to design
his triangular yard. The area of the yard is 400 ft. He
wants to find the area of the scale drawing.
Davis knows that the original area times the square of
the scale factor will equal the enlarged area. What is
the area of the scale drawing?
(Scale drawing)(Scale factor)? = Enlarged Area
Area = x
(x)(4)2 = 400
16x = 400
Area = 400 ft?
