Answer 2

Answer:

QUESTION :-

find breadth and area with l of 17 cm and perimeter of 60 centimetre.

SOLUTION :-

$perimeter = 2(l + b) \\ 60 = 2(17 + b) \\ 30 = 17 + b \\ 30 - 17 = b \\ 13 = b$

From here , we get b = 13cm

Now ,

$area \: = l \times b \\ 17 \times 13 = area \\ 321 {cm}^{2} = area$

Hence ,Area = 321 cm^2
