The area of a rectangle is the product of length and width. Here, you have the width being 2/3 the length. Put the given values into the area formula and solve.
A = L·W
864 ft² = L · (2/3·L)
1296 ft² = L² . . . . . . . multiply by 3/2
36 ft = L . . . . . . . . . . . take the square root

Answer:
5 1/6
Step-by-step explanation:
First you want to get the same denominator on both of the fractions. So you would multiply 1 2/3 or you can change it into a improper fraction which is a fraction greater than 1. So that would be 5/3 times 2/2. Because you want to get the same denominator. That is 10/6. Then you make 3 1/2 a improper fraction which is 7/2 and multiply it by 3/3 to get 21/6. Next you would add them together and get 31/6 but you have to simplify, so you would divide 31 by 6 and get 5 1/6.
