Question

A sqaure and a rectangular plot of land have the some perimeter. The square has side of 30m.The rectangle is of breath 1.5 dam.Find the area of the two plot.
​

Answer 1

Perimeter of square = perimeter of rectangle

perimeter of square = 4 × side

= 4× 30

= 120m

perimeter of rectangle = 2(l+b)

120 = 2(l+15)

120 = 2l+ 30

45 = l

area of square = s×s

= 30×30

= 900m²

area of rectangle = l×b

= 45×30

= 1350m²
