It is: 13 times 26 = 338 square feet
To get the area you multiply the length and the width. Doing the math gives an answer of 4,500 square feet.
4,200 square feet. Multiply length by width - the result is the area in square feet.
50 ft X 20 ft = 1000 sq.ft.,
9 square feet = 1 square yard Area = 31' x 50' = 1,550 square feet = 1722/9 square yards
A lot that is 50 feet wide by 500 feet long is equal to 0.57 acres. To calculate this, you multiply the length by the width (50 x 500 = 25,000 square feet) and then divide by the number of square feet in an acre (43,560 square feet).
A circle with a diameter of 77 feet will cover 4657 square feet.
There are two ways to answer your question. If you mean the circle is 16 feet wide (diameter), then the square footage is 201.06 square feet. However, if you mean the circle is 16 feet around (circumference), the square footage will be 20.372 square feet.
A circle with a 60-foot circumference has an area of 286.48 square feet.
A circle with a diameter of 18 feet has an area of 254.5 square feet.
A circle with a diameter of 24 feet has an area of 452 square feet.
A 45-foot diameter circle has an area of 1,590.4 square feet.
