Answer:
See answers below
Explanation:
Notice that the big trapezoid C consists of Two full squares and half od a square (that makes the right angle triangle left after folding the square)
so:
trapezoid C = 2.5 the size of the square
That makes the smaller trapezoid D = 1.5 the size of the square
and the triangle left = 0.5 the size of the square.
5.-
a) the square is 1/2.5 = 2/5 of C
b) the square is 1/1.5 = 2/3 of D
c) the square is 1/0.5 = 2 times the size of the triangle
d) the square is 1/1 = 1 of itself
6.-
a) Trapezoid C is 5 times triangle A
b) Trapezoid C is 2.5 = 5/2 of the square.
7.-
a) Trapezoid D is 3 times triangle A
b) Trapezoid D is 3/5 of trapezoid C
