Btw the answer has to be in fraction form if it’s a decimal then we will need to convert it into a fraction please help me

217 = 217/100 = 2.17

Step-by-step explanation:

18 1/12 ft = base length

Step-by-step explanation:

The area of a triangle of base b and height h is A = (1/2)(b)(h).

Since we want the measure of the base we solve this formula for b:

2A = (b)(h)

                                                                                                  2A

and then divide both sides to obtain a formula for b:  b =

                                                                                                     h

Substituting 217 ft^2 for A and 24 ft for h, we get:

b = 2*217 ft^2 / 24 ft = 18.0833  ft

If the answer must contain a fraction, take the 18 and hold it and convert the remaining 0.08333... to a fraction.  One way of doing this is to use a calculator.  On my old TI calculator, I would type in 0.0833333333..

and then press the MATH key and then select Option 1:  Decimal to fraction.

Doing this yields 1/12.  You can check this result by dividing:  1/12 = 0.08333...

Then the final answer, converted from 18.08333... ft, is

18 1/12 ft = base length
