To find the area of a rectangle, you multiply the length by the width. In this case, the length is 10 feet and the width is 3 feet. Therefore, the area of a 10ft by 3ft rectangle is 10 feet x 3 feet = 30 square feet.

The dimensions of a 10ft by 8ft area refer to its length and width. The 10ft measurement represents the length of the area, while the 8ft measurement represents the width. In this case, the area is rectangular, with a length of 10 feet and a width of 8 feet.
The area of the rectangle is the product of the length of the sides (provided the units of length are the same). Imagine a rectangle 6ft long and 10ft wide. You could even draw it if it helps. 6 multiplied by 10 is 60, so the area of a 6ft*10ft rectangle is 60ft2 or 60 sq. ft.
Area of a rectangle = (length) x (width) = 10-ft x 5-ft = 50 square feet
Inner radius of walk = R1 = 10/2 ft = 5 ft. Outer radius of walk = R2 = 5ft + 3 ft = 8 ft Area of fountain = pi*R12 = 78.54 sq ft Area of fountain + walk = pi*R22 = 201.06 sq ft So area of path = 201.06 sq ft - 78.54 sq ft = 122.52 sq ft.
14 ft 3 in - 3ft - 8in -1in = 10ft 6 inches.
