<span>perimeter of a rectangular rug is 30 yd
P= L+L+W+W
</span><span>P= 9+9+W+W
P= 18 + 2W
</span><span>18 + 2W = 30
2W = 30-18
</span><span>W= 12/2 = 6
A= L x W
A= 9 x w
</span><span>A= 9 x 6 = 45 yd square</span>
Answer:
21.98 square inches
Step-by-step explanation:
The formula is πd which means pi times the diameter. The value of pi is given (3.14) and the diameter is 7.
Multiply 7 times 3.14 to get 21.98
