630 square feet
Area is length times width. So a 12 by 7 room has an area of 84 feet2.
91 square feet (13 x 7 = 91).
7 ft *5 ft = 35 square feet.
The area equals the multiplication of length and width.Accordingly, the area = 7 feet x 10 feet = 70 square feet.
7*10 = 70 square feet
49 square feet. Multiply length by width - the result is the area in square feet.
Assuming the room measures 12 feet by 7 feet - and there is absolutely no reason to make that assumption as against 12 cubits x 7 cubits - the area is 12*7 = 84 square feet.
90-ft x 7-ft = 630 square feet
91 square feet. Multiply the length by the width. The result is the area in square feet.
Area = Width * Height = 11 7/12 * 6 = 69.5 Square Feet
90 x 7 = 630 sq ft
9 ft 3 in = 111 inches 7 ft 6 in = 90 inches 7 ft 2 in = 86 inches 111 + 90+ 86 = 287 / 12 inches in a foot = 23.916 linear feet
