Answer:
Below.
Step-by-step explanation:
The area = area of a rectangle on the same base and between the same parallel lines
= (15 + 6) * 8
= 21 * 8
= 168 yd^2.
The answer would be 15 but i am not sure what the problem says her answer is. if it is not 15 then her answer is wrong
A + b = 45
a - b = 21
a = 21 + b
Use substitution
21 + b + b = 45
2b = 24
b = 12
45 - 12 = 33
The numbers are 33 and 12
