The first figure, on left, is the composition of two areas, the area of a 7cm circle and the area of a 7 cm square so:
A=7^2+7^2π/4
A=49+49π/4
A=49(1+π/4) cm^2
A≈87.48 cm^2 (to nearest hundredth of a square centimeter)
...
The second figure is the area of a 15cm by 8cm rectangle minus the area of a 3cm circle so:
A=15(8)-3^2π/4
A=120-9π/4
A=120-2.25π cm^2
A≈112.93 cm^2 (to nearest hundredth of a square centimeter)
Answer is D.
Use that as the best solution for your question. It is tested and works better.
