Question

Mrs. Jackson is covering her bulletin board with new paper. What formula should she use to figure out how much paper to buy?

Answer 1

Answer:

Step-by-step explanation:

Something of this size could be measured in either ft² or in².

Area of a rectangle is determined by multiplying the width by the height.  In this case the bulletin board will be installed vertically, so let's say that

Area of board = (width)(height)

If, for example, the width were 6 feet and the height 3.5 feet, the area of this board would be (6 ft)(3.5 ft) = 21 ft²

Since 1 ft = 12 in, this 6 foot by 3.5 foot board would be 72 inches by 42 inches.

Answer 2

Answer: A = L x W

Step-by-step explanation:. Mrs. Jackson should use the formula to calculate area in order to figure out how much paper to buy. The formula is Area = Length x Width. This will tell her exactly how much paper she will need to cover the bulletin board.
