w′x′y′z′ is a dilation image of wxyz. which is the correct description of the dilation?

a) an enlargement with scale factor 2

b) a reduction with scale factor 1/2

c) a reduction with scale factor 2

d) an enlargement with scale factor 1/2

The answer is (C) a reduction with a scale factor of 2

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
