What is a formula of perimeter of rectangle?
Perimeter of Rectangle = 2 (Length + Width) Rearranging the terms in this formula, we get, 1/2 x (Perimeter) – Width = Length So, to find the length of a rectangle, subtract the width from half of the perimeter.
What is area formula for rectangle?
Area of Rectangle Formula
| The formula for the Area of a Rectangle | |
|---|---|
| Area of a Rectangle | A = l × b |
What is the formula of perimeter and area?
Area and Perimeter Formulas
| Shape | Area | Perimeter |
|---|---|---|
| Circle | A = π × r2 | Circumference = 2πr |
| Triangle | A = ½ × b × h | S = a+b+c |
| Square | A = a2 | P = 4a |
| Rectangle | A = l × w | P = 2(l + w) |
What is area and perimeter of square and rectangle?
● Area of rectangle = l × b; (l and b are the length and breadth of rectangle) ● Diagonal of rectangle = √(l² + b²) Perimeter and Area of the Square: ● Perimeter of square = 4 × S.
What is the area and perimeter of square and rectangle?
The perimeter of a rectangle is P=2b+2h, where b is the base (or width) and h is the height (or length). If a rectangle is a square, with sides of length s, the formula for perimeter is Psquare=2s+2s=4s and the formula for area is Asquare=s⋅s=s2.
What is the formula for perimeter and area of a square?
It is calculated by using the formula: Area = (side × side) square units. On the other hand, the perimeter of square is the total length of its boundary. It can be found by adding all four sides of the square or by multiplying any one side by 4. The formula to find perimeter of a square is (4 × side) units.
What is the area of a square and rectangle?
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. This is the same as saying length2 or length squared.
Which rectangle has the greatest area for a fixed perimeter?
This question does not have a numerical answer. A rectangle that measures 10 feet by 315 feet has an area of 3150 square feet. If you make the rectangle half as wide, it will measure 5 feet by 320 feet and has an area of 1600 square feet. Theoretically, a rectangle with a given perimeter can be infinitely long and thin.
How do you calculate the perimeter of a rectangle?
The relationship between area and perimeter of a square is that perimeter is 4 4 times the square root of the area.
What is the formula for finding the area of a rectangle?
To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply. A square is a rectangle with 4 equal sides. To find the area of a square, multiply the length of one side by itself.
How do you write algorithm to find perimeter of rectangle?
