Since you know that a square has four congruent sides, you know that the area is s2. If you want to find the length of one side, take the square root of both sides, so you're left with s= the square root of the area. A square has 4 sides, so to find the perimeter (4s = P), multiply both sides by 4. So you end up with this: P= 4A1/2 where P is the perimeter, A is the area, and the 1/2 means the square root. In simple terms, take the square root and multiply by four.
The perimeter is the sum of all of the sides of the triangle. If the shorter leg is x, the longer leg is 3x. The hypotenuse is then the square root of x^2 + 3x^2, or 2x. Then the perimeter is x + 3x + 2x, simplified, f(x) = 6x.
Measure its side in terms of feet. Multiply that measure by itself to give the area in square feet.
In terms of square footage, 0.2 acres = 8,712 square feet.
x = length of one side of square and r = radius of the circle therefore 4x = 2r * Pi therefore the radius of the circle is 2x/Pi therefore in terms of area x * x = Pi * ( 2x/Pi) * (2x/Pi) which gives a ratio of 1 : 4/Pi square area to circle area or 1 : Pi/4 circle to square x = length of one side of square and r = radius of the circle therefore 4x = 2r * Pi therefore the radius of the circle is 2x/Pi therefore in terms of area x * x = Pi * ( 2x/Pi) * (2x/Pi) which gives a ratio of 1 : 4/Pi square area to circle area or 1 : Pi/4 circle to squareNo, not as a universal rule. To illustrate, think of a piece of string that is 12 feet long. That piece of string can go around the perimeter of a square that is 3 feet on each side (i.e. adding up the 4 sides, each 3 feet long, would yield a square that has a 12 foot perimeter). The area of that same square would be calculated as 3 times 3 which equals 9 square feet. Now picture that same string going around a rectangle that is 2 feet wide by 4 feet long. This is thus a shape that also happens to have a 12 foot perimeter. But the area for this shape would be 2 times 4 which equals 8 square feet. Thus two different shapes with identical perimeters do not have to have the same area. This simple illustration with two common shapes (a square and a rectangle) that have identical perimeters but different areas can be extended to the odd shapes. Having the same perimeter does not lead to the conclusion that the shapes then have the same area. Hope this helps, I had to think about it myself!
To add and subtract algebraic expressions the simple rule of like terms applies. In your homework that asks for the expression represents the perimeter in units of this trapezoid you will need to find the like terms and simplify.
A perimeter is a length. It cannot be expressed in terms of area.
An expression is a collection of terms which are separated by addition or subtraction symbols. Often it represents one side of an equation or a formula.
Algebraic terms is when a letter, for example 'x', represents a number in a formula or sum.

I'm assuming that you meant the perimeter of a rectangle, not a square...The equation for the perimeter would be 2x + 2x + x + 25 + x + 25.You combine the like terms, and get 6x + 50.So the answer is 6x + 50.

in math terms, the perimeter is the measure around the shape.
