20 is the answer A+
A little less than 1/4 of an acre.
A - 20° = 90° - A ∴ 2A = 110° ∴ A = 55°
110 feet x 110 feet = 12,100 square feet (this, incidentally, is a very large room).
To find the area of a square, you multiply the length by the width. In this case, 90 ft x 90 ft equals 8100 square feet. This is because each side of the square is 90 feet long, so the total area covered by the square is 8100 square feet.
