Question

a wire in the shape of rectangle. it's length is 40cm and breath is 22cm if the same wire is rebent in the shape of square what will be the measure of each side ​

Answer 1

Answer:1) let the rectangle length =l =40cm

breadth =b =22 cm

let the side of a square = a cm

if the same wire is rebent in the shape of a square then

perimeter of a square=perimeter of rectangle

4a=2(l+b)

4a =2(40+22)

4a =2*62

a =2*62/4

a=31 cm

therefore side of a square = a =31cm

2) area of the rectangle =l*b= 40*22=880 cm^2

3)area of the square=a^2 = (31)^2 =961 cm^2

therefore

area of the square is more

Step-by-step explanation:

Answer 2

Length of the rectangle=40cm

Breadth of the rectangle=22cm

Perimeter of the rectangle =2*(l+b)

=2*(40+22)

=2*62

=124cm

Perimeter of the square=perimeter of the rectangle

Perimeter of the square = 124 cm

Side of the square = perimeter /4

=124/4

=31 cm

Therefore the side of the square is 31cm
