Question
Rectangle A has an area of 64 square meters. The length and width of rectangle B are 3 times the corresponding length and width of rectangle A. What is the area, in square meters, of rectangle B?
The correct answer is: 576
Area of rectangle A = lb = 64 sq.mts
The length & width of rectangle B are three times that of rectangle A
Length of rectangle B = 3 
l = 3l
Width of rectangle B = 3 b = 3b
Area of rectangle B = (3l)(3b) = 9 (lb) = 9(64) = 576 sq.mts
