Question

10. Two plots of land have the same perimeter. One is a square of side 64 m and the other is a
rectade of length 70 m. Find the breadth of the rectangular plot. Which plot has the
grader area and by how much?​

Answer 1

Answer:

The answer is:

Step-by-step explanation:

Perimeter of square: 64 x 4 = 256m

Perimeter of square = Perimeter of Rectangle

256 = 2(l+b)

256 = 2(70 + b)

256 = 140 + 2b

256 - 140 = 2b                      (Transposition process)

116 = 2b

b = $\frac{116}{2}$

                                   Hence breadth = 58m

Area of square = $64^{2}$

                        =4096$m^{2}$

Area of rectangle = 70 x 58  

                             =4060$m^{2}$

         Area of square is greater = 36$m^{2}$
