Question

Wire is in the shape of square of side 20 cm wire is bent into rectangle of length 24 cm find its breadth

Answer 1

Answer:

16 cm

Explanation:

when the same wire is used to make rectangle,the perimeter of square and rectangle remains same

perimeter of square= 4 ×side

= 4×20=80cm

so perimeter of rectangle=80 cm

now, perimeter of rectangle = 2(l+b)

2(l+b)= 80 cm

l=24 cm

2(24+b)=80 cm

24+b=80÷2=40

b=40-24

=16
