The width of a rectangle is the length of the shorter side.

measure it

To work out the area of a rectangle you simply multiply the width by the length:Here the width and length are 7 and 8 so by multiplying them together you get:56Remember, that if units are involved such as centimetres, you must write a squared sign after the digits. For example if it were 7cm and 8cm, you would write the answer as 56cm2

That is the definition of the area of a rectangle. It does not work for any other shape.

W = width of rectangle L = length of rectangle A = area of rectangle W x L = A (L+11) x L = A L squared + 11 L - 1302 = 0 solve for L by quadratic equation or by factoring: (L-31)(L +42) = 0 L = 31 W = L+11 = 42

The dimensions work out as length = 9 and width = 5

The perimeter of a rectangle is twice the width added to twice the length -> 2(W) + 2(L) We are told that for this rectangle the perimeter = 2(W) + 110 So for this rectangle 2(L) = 110 Therefore L = 55 But this does not tell us enough to work out the width ..... if the width is 1 cm then the perimeter would be 2(1) + 110 and if the width is 300 cm then the perimeter would be 2(300) + 110 In each case the perimeter meets the requirement of being 110 cm more than twice the width.

Length multiplied by width equals the area of a square or rectangle A=LxW Your answer will be in units squared.

To work out the area of a square or a rectangle, all you need to do is multiply the length by the width. In this case the room is the rectangle, and its length is 6 metres and its width is 4 metres. So its area is 6m x 4m = 24sqm.
