Since we know that length is twice the width, we can say that: Perimiter = 2(twice the width) + 2(width) Therefore, P = 2(2w) +2(w) this simplifies to P=6w Sine P=180, 160 = 6w, so w = 30 Because length is twice the width, length = 2 * width, or 2*30, which is 60
Remark The trick to this question is realizing what you took 1/3 of. Did you take it of the 150000 or is it 1/3 of some total you have to find. I don't think you could come up with a third choice.
It turns out that the answer is 1/3 of a number you don't know.
Equation (1/3) x = 150000 Multiply both sides by 3 3*(1/3) x = 150000 * 3 x = 150000 * 3 x = 450000
Conclusion The amount the company makes is 450000 dollars / year.
