Auston's office is 360 square feet. Calculate the area of his office in square yards.A) 1080 square yards
B) 120 square yards
C) 60 square yards
D) 40 square yards

Answers

Answer: D) 40 square yards

Step-by-step explanation:

We know that 1 yard = 3 feet

Given that Area of Austin's office = 360 square feet

To find the area of his office in square yards, we need to divide the given area by square of 3.

We know that square of 3= $3^2=9$

Thus, the area of his office in square yards= $(360)/(9) square\ yards$

Hence, the area of his office in square yards= $40\ square\ yards$

That is wrong i was taking a test the answer is going to be 40 square yards
