A rectangle has a length of (3x - 4) units and a width of (2x + 3) units.
What is the perimeter of the rectangle in terms of x?
A. (5x - 2) units
B. (5x + 14) units
C. (10x-2) units
D. (10x + 14) units
We know that the perimeter of a rectangle is \(2*(length+width)\) -why? (The perimeter is the sum of the outer lines of a figure, I.e. not the inside unlike area, so we add all lines) Since rectangle has 2 lengths and 2 widths thus adding a length and a width and multiply it by 2 is a correct formula.
Finding perimeter is just applying the rule,
simplify the bracket
So C. is the correct choice.
