Answer:
160 sq cm
Step-by-step explanation:
Since the two trapezoids are similar, you can use a ratio to find the area.
If we use x to represent the area of ABCD, then the ratio will look something like:
5/20 = 40/x
which then we can solve x to be 160 sq cm.
Answer:
13 and 53
Step-by-step explanation:
First Integer: x
Larger integer: 5x-12
66=x+(5x-12)
66= x+5x-12
66=6x+12
78=6x
13=x
First Integer: 13
Larger Integer: 13*5-12= 65-12=53
Check Work:
13+53=66
