How many square feet is in a 9'x19' room?
171ft2
Another garden in the shape of a parallelogram covers 76 square feet its height is 4 feet what is the base?
The height would allow you to calculate cubic feet. Square feet is length x width. seventy six square feet could 2'x38' or 4'x19' or 1'x76'.
What is the answer for 7.8 x19?

How high is a wall if the ladder is 18 ft high and 14 ft from the house?
The bottom of the ladder is 14 feet from the house and the ladder is an 18 foot ladder that reaches to the top of the house. The question is how tall is the wall of the house? I reworded it to show some assumptions I made about what you are asking.If these are not true, let me knowSo the ladder, the wall of the house and the distance from the ground to the house form a right triangle with hypotenuse 18 and base 14.Now, 142 +x2 =182where x is the height of the wall.Solving for x we find x=(Square root (324-196)=Square root 228since 228 is 4x57 the answer is2(square root (57)57 is 3 x19 so it won't help to simplify it more.
How many letter passwords can be formed from ABCs with no repeat?
That depends - on how many letters are in the password - AND - if any letter can be repeated. For example... an eight-digit password has 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 = 208,827,064,576 possible combinations IF every letter can b repeated. If each letter can only be used once, then the formula is 26 x 25 x 24 x 23 x 22 x 21 x 20 x19 = 62,990,928,000 possible combinations.
