Answer:

Step-by-step explanation:
From the question we are told that:


Generally the equation for Area of a sector A is mathematically given by




Assuming that the legnths given ae th sides o the room and th room is a recagnel
the diagonal makes 2 right triangles
pythagorean theorem
a^2+b^2=c^2
a and b are legs
c=hypotonuse
in this case
legnth and width are te legs and the diagonal is the hyptonuse
15^2+12^2=c^2
225+144=c^2
369=c^2
square root both sides
3√41ft=c
