Join the points `A (4,-4), B (4,4), C (-4,4), D (-4, -4)`, on `x-y` plane to get the square ABCD. Also find the perimeter and area of the square.

The diagonal of a square is 4cm long.Find its perimeter and area.

Show that the points : A (0,- 2), B (3, 1), C (0, 4) and D (- 3, 1) are the vertices of a square ABCD.

Find the perimeter of : a square of side 7.4 cm.

The two sides of the square are given by 4y-2 and y+1. Find the perimeter of the square.

Prove that the points A(0,1), B(1,4), C(4,3) and D(3,0) are the vertices of a square ABCD.

Write the ratio of perimeter to area of a square , having side 4cm.

In square ABCD, A=(3,4),B=(-2,4) and C=(-2,-1). By plotting these point on a graph paper, find the co-ordinates of vertex D. Also find the area of the square.
