A picture is 5 inches wide and 8 inches tall:

A rectangle is shown. The length of the rectangle is labeled 5 inches. The width of the rectangle is labeled 8 inches.

A photographer wants to use a scale factor of 2.5 to enlarge a picture. What will the area of the picture be after it is enlarged?

40 in2

250 in2

100 in2

81.9 in2

Answer 1

A = L * W
A = 5 * 8
A = 40

scale factor of 2.5

new rectangle :
A = L * W
L = 2.5 * 5 = 12.5
W = 2.5 * 8 = 20
A = 12.5 * 20
A = 250
