## 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 perimeter formula?

## 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 perimeter of all shapes?

## 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.
