What is perimeter formula?
The perimeter is equal to the boundary of the rectangle which can be calculated with the formula: Perimeter = Length + Length + Width + Width = 2(Length + Width) .
What is a formula of area?
The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle) . ... As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s 2 (square).
How do you find area and perimeter?
Multiply the length by the width to get the area, and add twice the length to twice the width to get the perimeter.
How do I find the perimeter and area of a rectangle?
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 rectangle?
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 we find area of a triangle?
The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle .
How do you calculate area?
The area is measurement of the surface of a shape. To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y . Find the area of this square.
What is work formula?
To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd . If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
How do you find the perimeter and area of a square?
| Table 2. Area Formulas | Shape Formula Variables | Square A=s2 s is the length of the side of the square. | Rectangle A=LW L and W are the lengths of the rectangle’s sides (length and width). | Triangle A=12bh b and h are the base and height |

What is the area and perimeter of square?
Answer: The area of a square is equal to the square of the length of its side and the perimeter of the square is 4 times the length of its side . Let the length of the side of a square be ‘a’ units. Explanation: The area of the square = a2 square units. The perimeter of the square = 4a units.
What is the formula for circles?
We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2 , where ( h, k ) is the center and r is the radius.
How do you find the length and area of a rectangle?
The area of a rectangle is the product of the breadth and length of a rectangle. A = L * W , where A is the area, L is the length, W is the width or breadth. NOTE: When multiplying the length by the width, always ensure you work in the same unit of length.
How do you find the side and 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. where A is the area, s is the length of a side, and · means multiply.
