Someone is trying to cheat on the Math homework.... how sad.

Improved Answer:
Let the unknown sides be x:
2x+x+3+x = 75
4x = 75-3
4x = 72
x = 18
2x = 36cm = the longest side

The perimeter of a square is atleast 22 inches what is the shortest possible length for each side of this square?
A square has four equal sides Perimeter of a square = 4 X length of a side Shortest possible length of a side is 22 inches divided by 4 sides = 5.5 inches
How do you figure the square feet of a rectangle trapezoid?
Find the average of the two sides (Longest length plus shortest length. Divide this addition by 2). Multiply the result by its height (which is the distance between the longest side and the shortest side).

2x=y x+3=z x+y+z=75 x+2x+x+3=75 4x=72 x=18 y=36 z=21
Which are measurements of the sides of a right triangle?
There are an infinite number of different right triangles. The only thing you can say about all of them is:(the square of the length of the shortest side) plus (the square of the length of the next shortest side)is equal to (the square of the length of the longest side)
How do i find the Ratio of the shortest to the longest side of a triangle?
You divide the length of the shortest side by the length of the longest side.
What is the ratio length of the shortest side to the length of the longest side?
Shortest side -------------------- Longest side

What is the longest length of a triangle if its shortest length is 3.6cm when two of its angles are 37.25 degrees and 48.4 degrees?
Largest angle: 93.25 degrees Shortest angle: 37.25 degrees Shortest length: 3.6cm Longest length: 3.6*sin(94.35)/sin(37.25) = 5.93cm to two decimal places

What is the length of the longest side the perimeter of the triangle is 63 in.?
The perimeter doesn't tell you the length of any of the sides. There are an infinite number of different triangles that all have the same perimeter. The only thing you can tell from a 63-in perimeter is that no side can be 31.5 inches or more.

What is the longest length of a trangle when its shortest length is 3.6cm if two of its angles are 37.25 degrees and 48.4 degrees?
The longest side is opposite to angle 94.35 degrees The shortest side of 3.6cm is opposite to angle 37.25 degrees The longest side is 3.6*sin(94.35) divided by sin(37.25) = 5.93cm
