Rug Dimensions Ac4Eaa
1. Problem: A rectangular rug has an area of 60 in.² and a perimeter of 34 in. We need to find its dimensions.
2. Let the length be $l$ and the width be $w$. The formulas are:
- Area: $A = l \times w = 60$
- Perimeter: $P = 2(l + w) = 34$
3. From the perimeter formula, solve for $l + w$:
$$2(l + w) = 34 \implies l + w = 17$$
4. Express $l$ in terms of $w$:
$$l = 17 - w$$
5. Substitute into the area formula:
$$l \times w = 60 \implies (17 - w)w = 60$$
6. Expand and rearrange:
$$17w - w^2 = 60 \implies w^2 - 17w + 60 = 0$$
7. Factor the quadratic:
$$w^2 - 17w + 60 = (w - 12)(w - 5) = 0$$
8. So, $w = 12$ or $w = 5$. Corresponding $l$ values:
- If $w = 12$, then $l = 17 - 12 = 5$
- If $w = 5$, then $l = 17 - 5 = 12$
9. Dimensions are $5$ in by $12$ in.
Final answer: The dimensions are 5 and 12 inches.
