A shed roof panel measures 10 feet by 14 feet and needs 2 coats of sealant. If one coat covers the panel once, how many total square feet of coverage are needed for both coats?

Correct answer to question 232 (Arithmetic Reasoning): 280 square feet

Method

One coat covers the full panel, 10 x 14 = 140 square feet, and a second coat repeats that coverage, so two coats need 140 x 2 = 280 square feet total.
