So basically this is made up a rectangle and a circel (two semicircles)

To find the area of a rectangle - 5*15 = 75.
The area of a circle with diameter 5 feet has radius 2.5 feet. so use pi*r^2 to get the area to be 19.63

Add these and get 94.63 and round that to 94.6

For the answer tot he question above, let the number of t-shirts are represented by 't'
number of sweaters are represented by 's'

cost of 1t=10 and cost of 1s=20 so
10t+20s=2000 or (factor out the 10 if you want to simplify)
10(t+2s)=10(200)
divide both sides by 2
t+2s=200

3x + 4y = 16 Subtract 4y from both sides. Put brackets around the 2 terms on the right.

3x + 4y - 4y = (16 - 4y)

3x = (16 - 4y) Divide by 3

$\text{ x =}\dfrac{(16 - 4y)}{3} = \dfrac{16}{3} - \dfrac{4y}{3}$
