Since opposite sides are equal in length and sides are perpendicular to each other, the quadrilateral ABCD is a rectangle.
Also length of rectangle is $A B = C D = 5 u n i t s$
and breadth of rectangle is $A D = B C = 7 u n i t s$
So Area of the rectangle $= l e n g t h \times b r e a d t h = 5 \times 7 = 35 s q u n i t s$

Plot the points A (4, 5), B (-1, 5), C (-1, -2) and D (4, -2) on a graph paper. Join AB, BC, CD and DA. Give a special name to the quadrilateral ABCD obtained. Also, find its area.

Since opposite sides are equal in length and sides are perpendicular to each other, the quadrilateral ABCD is a rectangle. Also length of rectangle is AB=CD=5units and breadth of rectangle is AD=BC=7unitsSo Area of the rectangle =length×breadth=5×7=35squnits
