Question

7. A rectangular piece of paper has a length of 16 cm and an area of 192cm. What is its perimeter​

Answer 1

Answer:

PERIMETER = 56cm

AREA OF A RECTANGLE = L×B

HERE,

L×B=192

the breadth has not been given to us so let us suppose it is x.

16x=192

x=192/16

x = 12cm

Thus the L = 12cm

so,

PERIMETER OF A RECTANGLE = 2(L+B)

2(16+12)

2×28

=56cm

PERIMETER OF THE RECTANGLE IS 56cm.
