Arectangle and a triangle have the same area. if their bases are the same length's, how do their lives compare? justify your answer.

Area of rectangle = l × b = height × base = bh
Area of traingle = ½bh'
Area of rectangle = Area of triangle (given)
bh = ½bh'
h' = 2h
It means that the height of the given triangle is double the height of the rectangle.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
