Question

If the perimeter of the sqare is 16 cm then its are is:-
(a) 64 cm2
(b) 81 cm2
(c) 121 cm2
(d) none of these​

Answer 1

Answer:

Given:

Perimeter of square=16cm

$side \: of \: square = \frac{perimeter}{4}$

putting values in above formulae

$side \: of \: square = \frac{16}{4}$

side of square = 4cm

$area \: of \: square = {s}^{2}$

Putting values in above formulae

$area \: of \: square = {4}^{2}$

$area \: of \: square = 16 {cm}^{2}$

none of these

Answer 2

Answer:

(d) . none of these

Step-by-step explanation:

perimeter of square is 4×side

so, 16cm=4×side

side= 16/4

side=4

hence area of square is side×side

=side ×side

=4×4

16square cm.
