Answer:
Step-by-step explanation:
<u>Area of the larger circle:</u>
<u>The shaded area:</u>
- π(2r)² - πr² = 75
- 3πr² = 75
- πr² = 25
<u>Area of the larger circle:</u>
We can write equations, using x and y as the length and width:
xy=40
2x+2y=26
Divide the second equation by two to get:
xy=40
x+y=13
Thus, x=13-y.
We now have (13-x)x=40, so
and
Factoring, we get:
(x-5)(x-8)=0
So, x can be either 5 or 8 (and y will be the other option). Thus, the length and width are 8 and 5.
