12 meters
Area = 150 square yards. A=l x w; Perimeter = 2(w + l): l = 6w; 2(w+6w)=2w + 12 w; 14w = 70; w=70/14=5; 6w = 30; therefore 5 x 30 = 150.
Take its length and multiply by its width. For example:- Length-30cm,Width-19cm Area=length x width =30x19(cm) =570 units2. Answer=The area of the rectangle is 570 units2. Note: Make sure to use the same units for length and width. The result is measured in units².

A prism. A rectangle is a special kind of prism. It is called a cuboid.
Formula: AlO2-
Divide the perimeter by 4, to get the length of one side. From there, you can easily calculate the area.
Formula: (C5H8)n
A rhombus has 4 sides of equal length and may be crooked and a rectangle must have four 90 degree angles. A square is both a rectangle and a rhombus.
Take its length and multiply by its width. For example:- Length-30cm,Width-19cm Area=length x width =30x19(cm) =570 units2. Answer=The area of the rectangle is 570 units2. Note: Make sure to use the same units for length and width. The result is measured in units².
