Assuming that the height of the rectangle is 2 (1/2 of 4)

radius=4/2=2

shaded=rectangle-semicircle
shaded=2*4-(1/2)pi2²
shaded=8-2pi
aprox
shaded=1.72

answer is 1.72yd²

2+4(7+2²)<br> --------------<br> 4×2+5×3

hodyreva [135]

Answer:

$\frac{46}{23}$

Step-by-step explanation:

$\frac{2 + 4(7 + {2}^{2} )}{4 \times 2 + 5 \times 3}$

$\frac{2 + 4(7 + 4)}{4 \times 2 + 5 \times 3} = \frac{2 + 4(7 + 4)}{8 + 5 \times 3}$

$\frac{2 + 4(7 + 4)}{8 + 15} = \frac{2 + 4 \times 11}{8 + 15}$

$\frac{2 + 4 \times 11}{23} = \frac{2 + 44}{23}$

$= \frac{46}{23}$
