Please help me on number 41!

Answer:
B) 1482
Step-by-step explanation:
First, find the area of the whole square : 46 times 37 equals 1702
Then find the area of the patio: 10 times 16 equals 160
Then find the area of the garden: 12 times 5 equals 60
Add the areas of the patio and garden: 160 plus 60 equals 220
Subtract 220 from the whole square
1702-220 = 1482
