Question

In the given figure. ABCD is a rectangle in which AB =
40 cm and BC = 25 cm. If P, Q, R, S be the midpoints
of AB, BC, CD and DA respectively, find the area of
the shaded region.

Answer 1

Answer:

500 cm^2

Step-by-step explanation:

QC = 25/2 = 12.5 cm

CR = 40 / 2 = 20 cm

area of ΔQRC = 1/2 * 20 * 12.5

                      = 125 cm^2

∴125 x 4 = 500 cm^2

∴40 x 25 - 500 = 500cm^2
