P = 56 so L + W = 28; L = 3W so 4W = 28 so W = 7 and L = 21
a rectangle has a perimeter of 72m. If the length is 20 m longer than the width find its dimensions?
The dimensions of a rectangle are the length and the width. With these two measurements , the area of the rectangle can be calculated : Area = length x width. The perimeter can also be found : Perimeter = (2 x length) + (2 x width).
You forgot to put in the length of the rectangle's perimeter.
Length = 9 Width = 9 Your rectangle is a square.
The dimensions of the rectangle are 21 units by 9 units

A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.
the perimeter of a rectangle is 700 yards. what are the dimensions of the rectangle if the lenght is 80 yards more than the width?
You forgot to put in the length of the rectangle's perimeter.
A rectangle has two dimensions, length and width. You haven't said what the width is. The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width. In general, the perimeter of a rectangle is twice its length plus twice its width.
Length = 9 Width = 9 Your rectangle is a square.
length + width = 20/2 = 10 length = 7cm, width = 3cm
The dimensions of the rectangle are 21 units by 9 units
If the given dimensions are the length and width of a rectangle then its perimeter is 15.6+4.5+15.6+4.5 = 40.2
Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.
If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)
