Given, Area of rectangle = Area of square
Area of rectangle = length x width
Area of square = side x side
Put the values , 144 x width = 84 x 84
Width = 84x 84 /144 = 7 x 84/ 12 = 7 x 7 = 49 m
Key takeaway: In GMAT, word problems based on only basic geometry are asked. You should remember simple formulae of perimeter, area of rectangle, square, circle etc. and their applications.
