A company offers blankets in two sizes: twin and double.

- The twin blanket is 24 inches longer than it is wide.
- The double blanket has the same length as the twin blanket but is 14 inches wider.
- The area of the twin blanket is 1,260 square inches less than the area of the double blanket.

a. Find the dimensions of the twin blanket.

b. Find the dimensions of the double blanket.

Answer :

Final answer:

The width of the twin blanket is 126 inches and the length is 150 inches. The width of the double blanket is 126 inches and the length is 140 inches.

Explanation:

To find the dimensions of the twin blanket, let's assume its width is x inches. According to the problem, the length of the twin blanket is 24 inches longer than the width. So the length of the twin blanket is (x + 24) inches. The area of the twin blanket is given by the product of its dimensions, so the area of the twin blanket is x(x + 24) square inches

Similarly, the width of the double blanket is also x inches. But the length of the double blanket is 14 inches wider, so the length of the double blanket is (x + 14) inches. The area of the double blanket is x(x + 14) square inches.

According to the problem, the area of the twin blanket is 1,260 square inches less than the area of the double blanket. So we can set up the following equation:

x(x + 24) = x(x + 14) + 1,260

Expanding and simplifying the equation, we get:

x^2 + 24x = x^2 + 14x + 1,260

Subtracting x^2 from both sides, we get:

24x = 14x + 1,260

Subtracting 14x from both sides, we get:

10x = 1,260

Dividing both sides by 10, we get:

x = 126

So the width of the twin blanket is 126 inches. And the length of the twin blanket is (126 + 24) = 150 inches.

The dimensions of the twin blanket are therefore 126 inches by 150 inches.

To find the dimensions of the double blanket, we use the same width, which is x = 126 inches. The length of the double blanket is (126 + 14) = 140 inches.

The dimensions of the double blanket are therefore 126 inches by 140 inches.
