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.
20 is the answer A+
110 x 90 = 9900
2 x 3 x 3 x 5 = 90 2 x 5 x 11 = 110
110 = 2 x 5 x 11
To find what percent 99 is of 90, divide 99 by 90 and then multiply the result by 100. This gives you (99 / 90) × 100, which equals 110%. Therefore, 99 is 110% of 90.
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%

-11 x -10 = 110 + -20 = 90
