Question

The perimeter of a square is the same as the perimeter of a rectangle. If the rectangle is
of size 105 cm by 15 cm, then find the area of the square.
moctangular have the same perimeter. The square

Answer 1

Answer:

3600 cm²

Step-by-step explanation:

perimeter of square = perimeter of rectangle = X

Length of rectangle = 105cm

Breadth of rectangle = 15 cm

Perimeter of rectangle = 2 x (l+b)

                                     = 2 x (105+15)

                                      = 2 x (120)

                                      = 2 x 120

                                      =240cm

Perimeter of square= perimeter of rectangle = X =240

Side of square = perimeter/4

                        = 240/4

                        =60cm

Area of square = S²

                        = S x S

                          = 60 x 60

                         = 3600 cm²
