Answer:
(A)
Step-by-step explanation:
Using the formula :
Area = 1/2 [-1(1 - 6) -7(6 - 1) -3(1 - 1)]
Area = 1/2 [5 - 35]
Area = 1/2 × -30 = |-15| = 15 units²
Convert the mixed number to inches. 3 feet 8 inches = 44 inches (12 inches per foot x 3 feet= 36 inches + 8 inches= 44 inches). 44 inches (length each section needs to be) x 4 (number of sections needed)=176 inches (total molding needed). To determine the amount of molding needed in feet, convert 176 inches into feet by dividing 176 inches by 12 inches. You get 14 2/3 feet, so the shortest board length is 15 feet.
