Answer: The distance around the lot is given by

Step-by-step explanation:
Since we have given that
Length of rectangular lot is given by

Width of rectangular lot is given by

We need to find the distance around the lot.
As we know the formula for "Perimeter of rectangle":

Hence, the distance around the lot is given by

To solve this problem, you can split the shape into a triangle and a parallelogram.
You can do this by imagining/drawing a line from point A to point C>
Now you can work out the area of triangle ACB
1/2 x b x h
1/2 x 5 x 3
= 7.5
Now work out the area of the parallelogram ACDE
b x h
5 x 3 = 15
Add the areas together and then you have the answer
7.5 + 15 = 22.5
The equation has to be set to something otherwise it is just an expression. I will assume that you mean 3x+60=0 in which case x equals negative 20
50 x 50 + 100 - 43 = 2557
