What is the name of the long and short sides of a rectangle?

In a rectangle, the longer side is referred to as the "length," while the shorter side is called the "width." These terms help distinguish the dimensions of the rectangle, with length typically representing the side that is longer. When discussing the area or perimeter, these dimensions are essential for calculations.

Does it matter which dimensions you select for the length and width when you find the area of a rectangle?

not really but the length is always the longer side :)


What is the length of a rectangle 3cm width and10cm w?

The length of the rectangle is 10 cm, while the width is 3 cm. In a rectangle, the length is typically the longer side, and in this case, it is indeed longer than the width. Thus, the dimensions of the rectangle are 10 cm by 3 cm.


Width and the length of a rectangle?

The width and length of a rectangle are two of its main dimensions. The width is the measurement of the shorter side of the rectangle, while the length is the measurement of the longer side. The area of a rectangle is calculated by multiplying the width by the length.


What is one dimension of a rectangle?

One dimension of a rectangle is its length, which is the longer side of the rectangle. The other dimension is its width, which is the shorter side. Together, these dimensions define the size and shape of the rectangle.


What is the answer to the question one side of a rectangle is thrice longer than its width if the perimeter of the rectangle is 28 cm what are the dimensions of the rectangle?

What is the length of a rectangle of 2cm going down and 5cm going across?

I am not sure what the point is for you to give us the dimensions of a rectangle and then ask what one of those dimensions is. Perhaps you are not sure whether the shorter or the longer of the two dimensions would be considered the length, and which the width. I would say that a rectangle measuring 2cm x 5cm is 2cm wide and 5cm long.

What is the length of the shorter leg of a right triangle if the longer leg has a length of 45 and the hypotenuse has a length of 53?

Subtract the squared longer leg's squared length from the hypotenuse's square to obtain the squared shorter leg length. Then find the square root of that answer for your final answer. In other words: 53 squared minus 45 squared equals your squared answer.
