Question

The length and breadth of a
rectangle are 20 m and 10 m
respectively. If its perimeter is
equal to the perimeter of a square,
find the side of the square.​

Answer 1

Answer: side of square = 15 m

Step-by-step explanation:perimeter of rectangle  =  perimeter of square

                                                 2(l+b)  =  4a

                                                  2(20+10)  =  4a

                                                   20 + 10 = 2a

                                                    30 =  2a

                                                      15 = a

                                                      side of square (a) =  15 m

Answer 2

The length and breadth of an rectangular area is 10m and 20m.

Then the area will be 10 × 20 = 200 sq.m
