Answer:
Below
Explanation:
Area of a triangle = 1/2 base * height
this triangle has base = 4 ( 3 in) = 12 in and height = 3 (3 in) = 9 in
area = 1/2 * 12 * 9 = 54 in^2
54 in^2 * $ 2.75 /in^2 = $ 148.50
If the window is scaled down by .5 then the dimensions would be
base = 6 in height = 4.5 in
area = 1/2 * 6 * 4.5 = 13.5 in^2
cost would be 13.5 in^2 * $ 2.75/in^2 =~ $37.13
