The name of the angle is obtuse
-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)
1 one is the answer
2 is the answer either
all the equations are in it's simeplest form
2 triangles of 4x3/2 each. So 12.
One 3x20 rect = 60
One 4x20 rect = 80
One 5x20 rect = 100.
So total <u>252</u>
