Mini-tangram
Joe cut out a cardboard rectangle 12.5 cm by 8 cm. He asked Penny to cut it into two pieces with one straight cut and then, with a second straight cut, to cut one of the pieces into two. Her problem was to work out where to make the cuts so that the three pieces could be arranged to form a square.
Penny found it quite easy once she realised that in each case one of the two cut pieces was a triangle.
What will be the area of the largest of the three pieces?
