Given the following data:
To calculate the length of the rectangle:
Mathematically, the perimeter of a rectangle is given by the formula;
[tex]P=2(L+W)[/tex]
Where:
Substituting the parameters into the formula, we have;
[tex]42=2(L+\frac{L}{2} )\\\\42=2L+L\\\\42=3L\\\\L=\frac{42}{3}[/tex]
Length, L = 14 meters.
