if you remember, the formula for the perimeter is:
The perimeter of a rectangle oceanfront lot is 190 meters.
So, P=190. Thus,
The first equation is
Dividing both sides by 2,
----2nd equation
The width is one-fourth of the length.
So, the next equation is:
If you substitute this to the 2nd equation,
Multiplying both sides by 4,
Dividing both sides by 5,
Since then,
Therefore, the dimensions of the rectangle is 76*19.
Power up,
