using this we can learn<span> that the maximum area that can be exclosed by this is 225, because the 2 perimeter lengths that define this rectangle would be 15 and 15.
</span>b(15)×h(15)=225(a)
therefore, your answer is 225 Units
<span>-I hope this is the answer you are looking for feel free to post your questions here on brainly in the future</span>
To understand the equation of a line which is perpendicular to x axis, let us consider the figure given below. In the figure above, clearly the line L is perpendicular to x-axis and passing through the value "c" on x- axis. Hence, the equation of a line perpendicular to x axis is x = c.
