Question

A wire is in the shape of a rectangle of length 16cm and breadth 9cm. If it is rebent in the shape of a square, what will be the measure of each side.? ​

Answer 1

perimeter of wire = 2( 16 +9)= 2 × 25 = 50 cm

therefore if it is bent in a square the perimeter remains same i,e 50 cm

therefore

4a = 50

a = 50/4 = 12 .5 cm

each side of square =12.5 cm

Answer 2

Answer:

hii....

here is your answer..... .

Given,

Length of rectangle : 16 cm

breadth :9 cm..

hence,

Its perimeter = 2(l +b)

=2(16+9)cm

= 2×25cm

= 50 cm

now,

perimeter of reactangle = perimeter of square,

So, according to question,

=> 50cm = 4 × side

=> side= 50/4

=>side= 12.5cm

So,

measure of each side : 12.5 cm

thanks

hope this will help u....
