Answer:
Your answer is 62 square inches
Step-by-step explanation:
You can cross off 1 & 2, as they are too small.
Lets split this up.
(2*3)+(2*3)+(3*5)+(3*5)+(2*5)+(2*5)
2*3 + 2*3 = 12
3*5 + 3*5 = 30
2*5 + 2*5 = 20
30+20+12 = 62
Step-by-step explanation:
to solve for a,
f(-1) = 5
a(-1)^2 + 1 = 5
a + 1 = 5, so a=4
