Look at the shaded shapes drawn on a square grid.
Steven says:
The area of rectangle A is double the area of square B.
a Is he correct?
b)
Explain your 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.

y = x + 95

y = 42 + 95

y=137 mm hg
