The perimeter of the rectangle is 76 units. Find the length of side pq
larisa [96]

Answer:   PQ=16\ units

Step-by-step explanation:

The missing figure is attached.

The perimeter of a rectangle is:

P=2l+2w

Where "l" is the lenght and "w" is the width.

You can identify in the figure that:

w=SR=PQ=2z+2\\\\l=QR=PS=3z+1

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

 76=2(3z+1)+2(2z+2)

Now you must simplify and solve for "z"

76=6z+2+4z+4\\\\76-6=10z\\\\70=10z\\\\\frac{70}{10}=z\\\\z=7

Finally, substituting the value of "z" into  PQ=2z+2, you get:

 PQ=2(7)+2=16\ units

The relevant formula for the area of the triangle is
.. A = (1/2)ab*sin(C)
.. = (1/2)*(2.75 mi)*(1.32 mi)*sin(35°)
.. ≈ 1.04 mi^2

The 4th selection is appropriate.
