Solve the problem.
-Sara is in charge of painting a mural on the side of a building. The wall is 47 meters long. The wall is 7x meters high up to the window ledge and it is 4y meters from the window ledge to the top. Write an expression with
Parentheses for the area of the wall. Then use the distributive property to write the expression without
Parentheses.
A)7x(4y + 47)= 28xy + 47 square meters
B)47(7x + 4y)= 329x + 188y square meters
C)47(7x + 4y)= 329x + 4y square meters
D)7x(4y + 47)= 28xy + 329x square meters

Quizplus · Accepted Answer

The area of the wall can be calculated by multiplying its length (47 meters) by its total height. The total height is the sum of the height up to the window ledge (7x meters) and the height from the window ledge to the top (4y meters). Thus, the expression for the area is 47(7x + 4y). Using the distributive property, this simplifies to 329x + 188y square meters.
