Upper primary school mathematics question UPQ353

Hairu likes to have his greeting card looks as the figure shown. ABCD below is a rectangle. BD is a straight line. What is the ratio of area X to area Y?

UPQ353-1

 

Solution:

 

            Line BD divided the rectangle ABCD to two equal triangles

            Similarly, area of triangle a = area of triangle

            And area of triangle c = area of triangle d

            Hence, the area of rectangle X = the area of triangle Y

            The ratio of the area of triangle X to the area of triangle Y = 1 : 1
