Question

the paper is in the form of rectangle ABCD is a rectangle in which AB is equal to 40 cm and BC is equal to 25 CM if pqrs be the midpoints of the sides ab BC CD and their respectively find the area of remaining part

Answer 1

Area of rectangle=l*b=40*25=1000cm2p is the midpoint of ABPB=1/2*40=20cmq is the midpoint of BCBQ=1/2*25=12.5cmArea of triangle PBQ=1/2*b*hArea of triangle PBQ=1/2*20*12.5Area of triangle PBQ=10*12.5Area of triangle PBQ=125cm2All four triangles are equal Area of 4 triangle =125*4Area of 4triangle =500cm2Area of shaded region =1000-500Area of shaded region =500cm2

Answer 2

Area is equal to 500cm2 .......
