Answer:

Equation:
30=2(x-2)+2(2x+3)


x:(14)/(3)

Explanation:

By definition, the perimeter of a figure can be calculated by adding the lenghts of its sides.

Knowing this, you can write the following equation:


P=2(x-2)+2(2x+3) [Equation 1]

According to the data given in the exercise, the perimeter in feet of the fighter is:


P=30

Therefore, you can substitute this values into [Equation 1]:


30=2(x-2)+2(2x+3)

Finally, you must solve for "x" in order to find its value. This is:


30=6x+2\\\\30-2=6x\\\\(28)/(6)=x\\\\x=(14)/(3)
