Question

find the perimeter of the rectangle whose length is 40cm and a diagonal is 41​

Answer 1

Answer:

Perimeter = 98 cm

Step-by-step explanation:

Now as given in the question,

Diagonal = 41 cm.

Length = 40 cm.

So, Putting these value we get,

Hence the width of the rectangle is 9 cm.

So 

The perimeter of the rectangle = 2 ( Length + Width )

                                                 = 2 ( 40 cm + 9 cm )

                                                 = 2 x 49 cm

                                                 = 98 cm 

Hence the perimeter of the rectangle is 98 cm.
