What is the formula for the surface area of a rectangle?
The area of a rectangle is the product of the two sides. One side is the height of the can, the other side is the perimeter of the circle, since the label wraps once around the can. So the area of the rectangle is (2 pi r)* h.
What is the surface area of the rectangular prism?
The surface area of a rectangular prism calculator gives us the answer: A = 2 * l * w + 2 * l * h + 2 * w * h = 2 * 8 ft * 6 ft + 2 * 8 ft * 5 ft + 2 * 6 ft * 5 ft = 236 ft² .
How do you find the length of a rectangle if you only have the width?
Double the width, and subtract that from the perimeter. Then divide that number by two, which gives you the length of the rectangle. Then, multiply the result by the width to get the area.
What is the formula to find width?
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
Which side is the length of a rectangle?
The length of a rectangle is the longest side, whereas the width is the shortest side.
What is the side of a rectangle?
4
What is the longer side of a rectangle called?
In fact, it is also called equiangular quadrilateral as all the angles are equal. There are many rectangular objects around you. Each rectangular shape is characterized by two dimensions, its length, and width. The longer side of the rectangle we call is the length and the shorter side is called width.
Can a rectangle have all equal sides?
Rectangle-rhombus duality The dual polygon of a rectangle is a rhombus, as shown in the table below. All angles are equal. All sides are equal.
Can a rectangle have 4 equal sides?
A rectangle has two pairs of opposite sides parallel, and four right angles. A square has two pairs of parallel sides, four right angles, and all four sides are equal. It is also a rectangle and a parallelogram. A rhombus is defined as a parallelogram with four equal sides.
How do you find the area and perimeter?
The perimeter of a two-dimensional shape is the distance around the shape. It is found by adding up all the sides (as long as they are all the same unit). The area of a two-dimensional shape is found by counting the number of squares that cover the shape.
