What shape has 4 sides with different lengths?
Rectangle: Like a square, a rectangle has four right angles and two pairs of opposite sides that are parallel.
Unlike the square, however, although opposite sides are equal in length, sides that share a corner — adjacent sides — may have different lengths..
How do I find the perimeter and area of a rectangle?
All rectangles are also parallelograms, but not all parallelograms are rectangles. The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.
How do you find the perimeter and area of a square?
Well, the formula for perimeter is simply 2 times length + 2 times width. In the case of our square, this would simply be 2x+2x (since length = width), or 4x . Therefore, if given an area, all you’d do is take the square root (to get from x2 to x , and then multiply by 4 to find perimeter.
What is a perimeter in math?
Perimeter is the distance around the edge of a shape. Learn how to find the perimeter by adding up the side lengths of various shapes.

How do you calculate an uneven area?
How to use irregular area calculator?Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other).Step 2: Enter length of horizontal sides into Length 1 and Length 2. And Width of the vertical sides into Width 1 and Width 2. … Step 3: Press calculate button. … Our Formula: Area = b × h.

What is the area and perimeter of square?
The area of a square with sides of length 1cm is 1cm². The area of other squares can be found by counting squares or by multiplying the length of the sides. The perimeter of a square is the total length of the four sides.

What is the formula for calculating area?
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
How do I calculate square footage?
Basic formula for square feet Multiply the length by the width and you’ll have the square feet. Here’s a basic formula you can follow: Length (in feet) x width (in feet) = area in sq. ft.
