Question

What is the perimeter of a map of a state park that is 16 in by 20 in after it is enlarged by a scale facto of 4 and then reduced by 50%?

Please help with this. Math is not my best subject at school. I really don't understand math.

Answer 1

144 inches

Explanation:

map = 16 x 20

(16 x 20) x 4 = 64 x 80

(64 x 80)/2 = 32 x 40 (final map width and length)

P= 2L + 2W = 2(40) +2(32) = 144 inches
