The area of the room is 150 square ft if the room is 7 1/2 inches long and 5 inches wide, option third is correct.
What is the area of the rectangle?
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
We have length of the room = 7 1/2 = 15/2 inches
Width of the room = 5 inches
Area of the room = (15/2)(5) = 75/2 square inches
Scale: 1/2 in = 1 ft
1/4 square inches = 1 square ft
1 square inches = 4 square ft
= (75/2)×4
= 150 square ft
Thus, the area of the room is 150 square ft if the room is 7 1/2 inches long and 5 inches wide, option third is correct.
