Question

"
A wire is in the shape of a rectangle. Its length is 40 cm and breadth is 22 cm. If
same wire is rebent in the shape of a square, what will be the measure of each side
Also find which shape encloses more area?​

Answer 1

Answer:

Step-by-step explanation:

perimeter of rectangle=2(l+b)

=2(40+20)

= 2×60=120cm

perimeter of rectangle=perimeter of square

4a=120

a=30

side of square=30cm

area of rectangle=l×b

=20×40=800cm^2

area of square= 30×30=900cm^2

hence,square shape encloses more area

Answer 2

Answer:

side of square is 32 cm

square (1024 cm^2) encloses more area than rectangle (880 cm^2)

Step-by-step explanation:

let side of square is a

perimeter of rectangle=perimeter of square

40+40+22+22=4*a

124= 4a

a=32cm

area of square= 32*32=1024cm^2

area of rectangle=40*23=880cm^2

so area of square is greater than the area of rectangle.
