Strike441 [17]

Answer:

The total area of the flag was 394 square inches.

Step-by-step explanation:

Given that Rainey's group designed a flag, and they used 234 square inches of green fabric, twice as much green fabric as orange fabric, and 3 times as much green fabric as yellow fabric and they had 35 sq inches of yellow fabric left, to determine the total area of the flag the following calculation must be performed:

234 + 234/2 + (234/3 - 35) = X

234 + 117 + (78 - 35) = X

234 + 117 + 43 = X

234 + 160 = X

394 = X

Thus, the total area of the flag was 394 square inches.
