Question

Mona has a triangular flag. She wants to cut out a similar flag that has dimensions one-fourth of the original flag. If the area of the original flag is 320 square inches, what is the area of the new flag that Mona cuts out?
Answer
16 in2
20 in2
32 in2
80 in2

Answer 1

320 / 4 = 80

Answer 2

thanks

Answer 3

If two polygons are similar, the square of their scale factor is equal to the ratio of their areas.
(1/4)^2 = x / 320 where x is the area of the smaller flag
1/16 = x / 320
x = 20
