Question

a wire is bent from a rectangle of
28m × 10m. it is again straightened and bent now to form a square. what is the side of the square so formed

give answer in detail​

Answer 1

Step-by-step explanation:

The perimeter should remain constant.

Perimeter of rectangle= 2(l+b)

=2(28+10)

=2(38)

=76

Let the side of the square be a.

perimeter of square is 4a.

4a=76

a=19 m

So, the side of the square is 19m.

Answer 2

Answer:

19.5 cm

Step-by-step explanation:

Perimeter of rectangle- 2(L+ B)

                                        2( 28+10)

                                       2(38)

                                        76cm

Perimeter of Square- 4S

                                  76= 4S

                                   76÷4= S

                                     19.5 cm= S
