It depends on whether you want the width as a fraction of the length or perimeter or something else - like the diagonal.
well mine is 4cm wide and 45 cm long
To find the answer you would do 161 divided by 14 because width plus length equals area. You just do the problem backwards. the answer ends up being width=11.5cm
Yes (apart from units):If the side of a square is 4cm then itsperimeter is 4cm + 4cm + 4cm + 4cm = 4 x 4cm = 16cm;area is 4cm x 4cm = 16cm2
Let the length be 2x and the width be x: Perimeter = 2(2x+x) = 84 4x+2x = 84 6x = 84 Divide both sides of the equation by 6 to find the value of x: x = 14 Therefore: length = 28cm and width = 14cm
