and I will mark you brainliest

but ANSWER should be right ​

Answer 1

Answer:

P=2(l+w) apply this formula you will get the answer.

Answer 2

Answer:

$D^{2} =L^{2} +B^{2} \\\\41^{2} =40^{2} +B^{2} \\1681=1600+B^{2} \\1681-1600=B^{2} \\\sqrt{81} =B\\9=B$

PERIMETER OF RECTANGLE IS= 2(L+B)

            =2(40+9)

             =98cm^2
