Answer: 150ft^2

Step-by-step explanation:

length: 7\frac{1}{2}in Convert to an improper fraction. \frac{7*2+1}{2}=\frac{15}{2}

width: 5 in

Formula: A=w*l

A=(5in)(\frac{15}{2}in)\\A=\frac{75}{2}in^2

Convert to ft. I assume your conversion factor is \frac{1}{2}in. : 1ft. However, the unit we need is squared. Square both sides.

(\frac{1}{2}in.)^2 : (1ft)^2

\frac{1}{4}in^2 : 1ft^2

Convert.

\frac{75}{2}in^2(\frac{1ft^2}{\frac{1}{4}in^2 } )=

Invert the fraction in the denominator and multiply it by the numerator.

\frac{75}{2}in^2*1ft^2*4in^-^2=75*2ft^2=150ft^2

The length of AD is 75. Since opposite sides have the same length, 63 plus 63 is 126. The perimeter is 276, so 276 minus 126 is 150. 150 divided by 2 is 75.

Point G is between F and H. FH= 102, FG=5x+9, and HG=9x-5
dexar [7]

a)

FH = 102, FG = 5x + 9. HG = 9x - 5     <em>Given</em>

  FG    +   HG   =    FH                        <em>Segment addition postulate</em>

5x + 9 + 9x - 5 =  102                         <em>Substitution</em>

            14x + 4 = 102                        <em>Simplify (added like terms)</em>

                  14x = 98                          <em>Subtraction property of equality</em>

                     x = 7                             <em>Division property of equality</em>

b)   FG = 5x + 9  = 5(7) + 9   = 35 + 9   = 44

c)   HG = 9x - 5   = 9(7) - 5   = 63 - 5   = 58

Answers: a = 7, b = 44, c = 58
