Area of Triangle: 4.5m
height is 4.5m
base is 2m
overall height is 10m so 10-3.5-5= height of triangle
overall base is 10.75m so 10.75-3.25-2.5-3= base of triangle
Area of the smallest rectangle: 13.5m
base is 3m (provided)
height is 4.5m (same as triangle)
Area of the medium sized rectangle: 16.25m
base is 2.5m (provided)
height is 6.5
overall height is 10m so 10-3.5= the height of this rectangle
Area of largest rectangle: 32.5
base is 3.25m (provided)
heigh is 10m (provided)
