Question

pls solve in copy

once already I have asked this question but the answer that I get is wrong​

Answer 1

Step-by-step explanation:

perimeter= 2(l+b)

perimeter = 2( 32/2 + 39/4)

perimeter= (128 + 117/12)

perimeter = 2(245/12)

perimeter = 2×245/12

perimeter= 41 m.

area = l×b

area = 32/3 × 39/4

area = 104 m

Answer 2

Answer:

As perimeter of rectangle = 2(l+b)

Then perimeter= 2( 32/2 + 39/4)

= 2( 128 + 117/ 12)

= 2( 245/12)

= 2 × 245 /12

= 490/12

= 41

Therefore, perimeter is 41cm.

As area = length× breath

So, area = ( 32/2 ) × ( 39/4)

= 104m2
