2_x_ + 2(x – 4) = 45

It is: 12 units in length

The length is usually taken to be the longer of the two sides of a rectangle. In this case, therefore, the length is 36 metres.

a rectangle has a perimeter of 72m. If the length is 20 m longer than the width find its dimensions?

Let the length be x+4 and the width be x:- Form a quadratic equation: (x+4)*x = 45 => x^2 +4x -45 = 0 Solving the equation: x has a positive value of 5 Therefore length is 5+4 = 9 feet and width = 5 feet Check: 9 times 5 = 45 square feet

No. length is usually the bottom. Furthermore, a rectangle doesn't necessarily have a longer side. A rectangle simply needs 4 right angles. Therefore a square is a rectangle, yet has no longer side.

i don't know what length of rectangle is 7 cm longer than the width the perimeter of the rectangle is 46 cm .what is the length of the of the rectangle ?

Area of a rectangle is length times width, therefore if the length is two feet longer than the width then the length is 9 and the width is 7, when they are multiplied you get 63

Yes, the length of a rectangle is generally understood as the longest side(s).

Assuming there is no border around the circle, then doubling the radius will give the length and width of a square (28 x 28 = 784cm2). The problem in your question is that you state it is a rectangle. Which means that the rectangle must be longer in length then width!

Conventionally, it would be the measure of the longer sides.The length is that of its longest side.
