Question

14. Which has greater perimeter a square ground of side 85 m or a rectangular ground with sides 10 m and 75 m and by how much. ​

Answer 1

Perimeter of Square is greater than that of rectangle by 170 m²

Answer 2

Here side of square is 85 m

Perimeter of square = 4 × side

                                 = 4 × 85

                                = 340 m

Perimeter of rectangle = 2 (length + breadth)

                                     = 2 ( 10 + 75)

                                    = 2 ( 85 )

                                    = 170 m

So, the perimeter of square and rectangle are 340 m and 170 m respectively.

So, the perimeter of the square is more than that of the rectangle.
