-The perimeter is the length of the line if the whole rectangle was straightened out.
-a rectangle has 2 sets of 2 even sides. The top and bottom width would be equal and the two heights would be equal
Armed with these two facts we know the perimeter would be Side A + Side B + Side C + Side D
9.35 + 9.35 + 6.82 + 6.82 = ?
The actual formula for a rectangle or even a square is
2(length + width)
what? um child.... anyways
Area of a pyramid is ⅓ * area of Base * height
or ⅓ * 144 * 42 or 2016 cm³
