18. Two plots of land have the same perimeter. One is a square of side 60 m, while the other is a rectanglewhose breadth is 1.5 dam. Which plot has the greater area and by how much?​

Answer» SQUARE perimeter = 4a = 4*60 = 240 m
Square area = 60*60 = 3600 m2

Rectangle perimeter = 2(l+b)
240 = 2(l+15)
120-15=l
l=105

Area = 105*15 = 1575m
Square has larger area
