Answer:
a. 312cm^2
Step-by-step explanation:
You find the area of the rectangle
4 * 6 = 24
Then you find the area of the trapezoid
(10 + 6) * 5 / 2 = 40
Multiply 40 * 2 since there are two trapezoids
40 * 2 = 80
Add the of one bow
80 + 24 = 104
multiply it by 3 since you need 3 bows
104 * 3 = 312
Your answer is 312
