Can you show the paper more? I can't see what I need to know in order to solve it...
Answer:
357_²
Step-by-step explanation:
find the area of the cut out triangle
20 * 21 = 240
240/2 = 210
find the over all area
21 * 27 = 567
subtract the missing piece
567 - 210 = 357
The hypotenuse is the longest side of the triangle and also the one that is across from the ninety degree angle.
Answer:
Step-by-step explanation:
The decimal forms of some real numbers, like , terminate, while the decimal forms of other real numbers, like , do not terminate, but have a repeating pattern. Still other real numbers, like , have decimal forms that neither terminate nor repeat.
3 inch by 5 inch
A = L * W.....A = 3 * 5....A = 15 inches^2
if it is enlarged by a scale factor of 2...
3 x 2 = 6
5 x 2 = 10
Area = L * W......A = 6 * 10...A = 60 inches^2
if reduces by a scale factor of 1/2..
3 x 1/2 = 3/2 = 1.5
5 x 1/2 = 5/2 = 2.5
A = L * W....A = 1.5 * 2/5....A = 3.75 inches^2
