attashe74 [19]

The square mural in Olivia's classroom has dimensions x by x.

Then she paints a mural of dimensions: x+5 (the length) by x-2 (the width).

Thus the second mural (the hallway mural) has the shape of a rectangle with dimensions (x+5) by (x-2), so the area of the second mural is
(x+5)(x-2).


each side of the classroom mural is 7 feet means that x = 7 ft,

thus the area of the hallway mural is :
(x+5)(x-2)=(7+5)(7-2)=12*5=60 (square feet)

Answer:
C. (x + 5)(x – 2); 60 square feet
