Question

A worker is printing rectangular bulletins. The area of a bulletin is represented by 2.5w², where w represents the width of a poster. What is the area, in square inches of a bulletin with a width of 12 inches.​

Answer 1

To calculate the area of the bulletin with a width of 12 inches, substitute 12 for 'w' in the given formula 2.5w², which equals 360 square inches.

Step-by-step explanation:

The student is asking about finding the area of a rectangular bulletin, given an algebraic expression that represents the area in terms of the width of the bulletin. The area of the bulletin is represented by the expression 2.5w², where w is the width. To find the area when the width is 12 inches, we substitute 12 in for w in the expression:

Area = 2.5w²

Area = 2.5(12²)

Area = 2.5(144)

Area = 360

Therefore, the area of the bulletin with a width of 12 inches is 360 square inches.
