Answer:
28 squares
Step-by-step explanation:
column is 7 squares long, row is 4 squares long, 4x7 = 28 squares
B + G = 5273
G = B + 231
B + B + 231 = 5273
2B + 231 = 5273
subtract 231 from both sides
2B = 5042
divide both sides by 2
B = 2521
G = 2521 + 231
G = 2752
There are 2752 girls and 2521 boys LETTER D
