Answer:
In Algebraic Area = (x + L) (x+W) Whole square or whole rectangle
In Scale Area = (S x L) (S x L) Whole square or whole rectangle
Triangle
(L x W) = (B x H)
In Algebraic Area = 1/2 x b x h
b x h
= -------------
2
Step-by-step explanation:
If the rectangle shows only diagonal lengths then use triangle and Pythagoras to work out height (length) or base.
In any case height or base is shown you can multiply similar to how you would multiple length and width. For 4 sided shapes we do not 1/2 we only 1/2 when they are triangles.
