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.

110 x 90 = 9900
2 x 3 x 3 x 5 = 90 2 x 5 x 11 = 110
110 = 2 x 5 x 11
110% of 90 = 99
What is the product of 110 and 90
110% of 90 = 99
If: x+x2 = 110 then x = 10 which is the solution
90 = 100% 25 = X% X = 25x100 ÷ 90 X = 27.777777777777%
-20
-11 x -10 = 110 + -20 = 90
