3w - 2 = 2w + 3 Add 2 to both sides: 3w = 2w + 5 Subtract 2w from both sides: w = 5
Using basic algebra we can solve this problem. First we need to write out the problem:5-32+2w = -7-27+2w = -72w = 20w = 10
In this rectangle we'll call the length L and the width W We know that L + 3 = 2W So, if we subtract 3 from each side we get L = 2W - 3 We also know that 2L + 2W = 18 Now we can substitute the L terms 2(2W - 3) + 2W = 18 4W - 6 + 2W = 18 4W + 2W = 18 + 6 6W = 24 W = 4 So, if L + 3 = 2W then L + 3 = 8.... therefore L = 5 So now, we'll check that the measurements we've ended up with work out... 2L + 2W = 18 5 + 5 + 4 + 4 does indeed = 18
The perimeter is the total of all 4 sides of the rectangle, and a rectangle, by definition, has 2 sets of parallel sides. Perimeter = 2L + 2W (where L = length of ONE side, and W = width of ONE side). So, for example, if the perimeter is 40 cm, and the length is 15 cm, you figure out the width by subtraction and division. P = 2L + 2W 40 = 2(15) + 2W 40 = 30 + 2W 40-30 =30 + 2W - 30 10 = 2W 10/2 = 2W/2 5 = W So the width of the rectangle is 5 cm.
