Question 3: 12 points

Answer 1

Answer:

$9x^{5}y^{5}$ yards.

Step-by-step explanation:

Given that the area of a rectangle (A) is $45x^{8}y^{9}$ square yards.

If the length of the rectangle (L) is given to be $5x^{3}y^{4}$ yards, then we have to find the width (W) of the rectangle in yards.

Now, A = L × W

⇒ $W = \frac{A}{L} = \frac{45x^{8}y^{9}}{5x^{3}y^{4}} = (\frac{45}{5})\times (\frac{x^{8}}{x^{3}}) \times (\frac{y^{9}}{y^{4}}) = 9x^{8 - 3}y^{9 - 4} = 9x^{5}y^{5}$ yards. (Answer)
