- Midpoint Formula:
So firstly, let's start with the x-coordinates. Since we know the midpoint's x-coordinate and point A's x-coordinate, we can solve for point B's x-coordinate as such:
Next, do the same thing except solve for the y-coordinate and using point A's y-coordinate and the midpoint's y-coordinate:
<u>Putting it together, point B's coordinates are (2,4).</u>
we know that
A half-acre is equal to---------->
Let
x---------> the length side of the building lot
y--------> the width side of the building lot
A------> Area of the building lot
x=5y-------> equation 1
--------> equation 2
substitute equation 1 in equation 2
<u>Find the value of x</u>
therefore
<u>the answer is</u>
the dimensions of the building lot are 100.55 m* 20.11 m
