Answer:
102.849
Step-by-step explanation:
the perimeter of the square is just 4 × 18.
for the semi-circle the perimeter should be R(pi + 2)
so the perimeter of a semi circle is 30.849
add both values for the final answer which is 102.849
Area of the 2 right triangles =2 (1/2 x 1.5 x 2 ) = 3 in²
Area of the 3 rectangles = (1.5 + 2 + 2.5) x 11 = 66 in²
Total Surface area = 3 + 66 = 69 in²
Answer: 69 in²
