The length of a rectangle is 3 meters more than 2 times the width the area is 77 meters squared what is the length and width?
Let's call the lendth x and the width y x = 2y + 3 xy = 77 That is what is know in the trade as a simulataneous equation Because we have an x on its own lets substitute that equation into the second. (2y + 3)y = 77
2y2 + 3y = 77 2y2 + 3y -77 = 0 (2y - 11)(y + 7) = 0 y = 5.5 or -7 You don't get recangles with negative lengths so:
y = 5.5 We can then substitute that into one of the equaitons to find x x = 2y + 3 x = 2*5.5 + 3 x = 14 So the length is 14 and the width is 5.5

The perimeter of a rectangle is 50 meters and its length is 12 meters. What is the width of the rectangle?
The width of the rectangle is 13 meters. The perimeter of the rectangle is 50 meters, and its length is 12 meters. The 50 meters is 2 times the length plus 2 times the width. With a length of 12 meters, twice that is 24 meters. That leaves 50 meters - 24 meters for twice the width. And 50 - 24 = 26, which is twice the width. The 26 meters divided by 2 = 13 meters, which is the width of the rectangle.
