diagonal is 7 cm.
(please write the full answer it is urgent i will mark as brainlist please write the full answer)

★ Given :-

★ To Find :-

★ Diagram :-

➳Let the side of the square be x cm.

➳Now, we know, each sides of square is of equal length.

➳Now, let the square be ABCD ( according to the attachment)

➳Therefore, AB = BC = CD = DA = x cm

➳The diagonal has divided the square into two triangles.

➳Now the each angles of a square is of 90°

➳Therefore, ∠DCB = 90°

➳And △DBC is a right angle triangle.

➳ Therefore, the side of the square = 4.95 cm

Now, the perimeter = 4 × side

➳ Therefore, the perimeter of the square is 19.8 cm^2
