The width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.
<h3>How to determine the dimensions</h3>
The formula for determining the area of a rectangle is expressed as;
Area = width × length
Given that;
- Area = 84 square feet
- length = 2w
Let's substitute into the formula
84 = w(2w)
84 = 2w²
Divide both sides by 2
84/ 2 = w²
42 = w²
Take square root of both sides
w = √42
w = 6.4 feet
Length = 2w = 2 × 6. 4 = 12. 96 meters
Thus, the width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.
