Answer:
(A) 49
Explanation:
Most of the equation is just explaining what length and width is.
Area = L (length) · W (Width)
Option One:
Length: 9
Width: 5
9 · 5 = 45
There is no option for 45 so we need to check option two.
Option Two:
Length: 7
Width: 7
7 · 7 = 49
There is an option for 49, so that is our answer.
Basically, they are just explaining that Area = L · W, and to check both options to see if there is an answer.
