Answer 1

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? (5 points)

40 in2
250 in2
100 in2
81.9 in2

Answer 2

This is the same idea as the other question :)

we do "scale factor" times the original side lengths

so 5 times 2.5
and
8 times 2.5

Answer 3

i got 20 and 12.5

Answer 4

because the area for a rectangle is base times height

Answer 7

Answer 8
