It is: 6*14 = 84 square feet
To get the area, you must times the width and length. 10.5 x 8 = 84 So your answer is 84 square feet.
To find the circumference of a circle when given the diameter, you can use the formula C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter. Given the diameter of 84cm, you can plug this into the formula to get C = 3.14159 * 84 = 263.893cm. Therefore, the circumference of the circle is approximately 263.893cm.
A foot IS a linear measure so a foot is a linear foot. So 84 linear feet is 84 feet.
