Question

Find the perimeter of a rectangle whose length is 30cm and width 0.3m​

Answer 1

Answer:

60.6cm

Step-by-step explanation:

Perimeter of rectangle = 2×(l+w)

= 2×(30 + 0.3)cm

= 2 × 30.3cm

= 60.6cm

Answer 2

perimeter of rectangle=2(l+b)

here, l=30cm and b=0.3m

Converting length into meters= 30/100=0.3m

Now by applying formula

we give,

=2(0.3+0.3)

=2×0.6=1.2m

perimeter of rectangle is 1.2m
