Re: Can you do this national exam question for primary school kids?

28

WS=a
WX=b
XV=c
VQ=d

a*b=8
c*d=32

b+c=6
a+d=15

a/b=c/d => b*d=16, a*c=16

from a*c=16 => (15-d)*c=16 => 15*c-32=16 => c=48/15 => d=32*15/48=10
=> b= 5-48/15=42/15

area of rectangle C= b*d =10*42/15= 28

The area of the whole rectangle is 15*6=90 cm2.
The rectangle consists of two identical triangles. So, the area of one triangle is 45 cm2.
This triangle consists of triangle A, rectangle C and another triangle, identical to triangle B.
So, the area of rectangle C is: 45 cm2 - 4 cm2 (triangle A) - 16 cm2 (triangle B) = 25 cm2.
