anonymous · Answer

Use the formula 1/2(bh) for triangle area.
Use the formula ab for the rectangle 
1/2(12)(8)
24sq ft.=ab 
hint: it's 4 sides that are equal.  solve

anonymous · Answer

why will its 4 sides be equal if it's a rectangle?

anonymous · Answer

sorry typo I Meant 2 sides because Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor.
