10 + 18 = 28 10 x 18 = 180
Find the area of an equilateral triangle if its perimeter is 18 ft
The square root of 324 is 18 and 4*18 = 72 units of measurement which is the perimeter of the square.
18*sqrt[3]
The Strategy Room - 2008 - 2011-10-18 was released on: USA: 18 October 2011
To calculate square footage, you multiply the length by the width of the room. So, if the room measures 10 ft. by 18 ft., your total area is 180 sq. ft.
10*18=180sq ft
You would find the area by multiplying the width by the length, so the area would be 216 square feet.
Area = 15*18 = 270 square units of measurement
It depends on whether the tiles are 18 inch * 18 inch or 18 cm * 18 cm, etc. And also on whether the room is 10ft *10ft or 10 yards*10 yards or 10 metres*10 metres etc.
252 square ft. Since the room is rectangular, you find the area by multiplying the length and the width, in this case being 18 and 14. 18x14=252 so the area, which is always in square units, is 252 square feet.
If the end is 18 by 10 high and the length of the prism is 24, the surface area is 2 x 1/2 x 18 x 10 + 18 x 24 + 10 x 24 + sqrt(100 + 324) x 24 = 1346.19
To find the area of 11 and 18 you multiply it.

Area = Length * Width= 18 * 18 = 324 Square Feet
Assuming the room is 20 ft by 18 ft (the question does not say so), the area would be 20*18 = 360 square feet
