In the figure, every region is a square. If the yellow squares have area 1, then what is the area of the whole rectangle?
Yellow squares have area 1 so the sides = 1
Which makes the purple squares sides = 2
Which makes the brown squares sides = 5
Area of brown squares .... 2 squares with area 52 each = 2 • 25 = 50
Area of purple squares .... 2 squares with area 22 each = 2 • 4 = 8
Area of yellow squares .... 2 squares with area 12 each = 2 • 1 = 2
Add up all six areas .... total area = 60 square units
