Hi there! The answer is w = 3.75
I suppose we're talking of a rectangle. The area of a rectangle can be found with the formula A = W * L. Therefore, the width can be found by dividing the total area by the length.
[tex]w = 5 \frac{5}{8} \div 1 \frac{1}{2} = \frac{45}{8} \div \frac{3}{2} = \\ \frac{45}{8} \times \frac{2}{3} = \frac{90}{24} = 3 \frac{18}{24} = 3 \frac{3}{4} =3.75 [/tex]
