15 * 20 = 300 square feet.
A 15 x 15 foot room has 225 square feet of floor area. The area of a rectangle is length times width. Yes, this is a square, but a square is a special form of rectangle. This …square is 15 feet long and 15 feet wide, so 15 feet x 15 feet = 225 square feet for the math.
A 15 foot by 18 foot room will have 270 square feet of area. Area equals length times width, and 15 x 18 = 270, so a room with those dimensions in feet will have 270 squa…re feet of floor space.
240 square feet. (16 x 15 = 240)
375 square feet. (area = length x width)
15 times 20 equals 300 square feet. Isn't there a "calculator app" in your phone for this?
225 square ft.
20 x 15 = 300 square feet.
15 feet x 15 feet = 225 square feet.
16.97 square feet
585 ft2 Start by dividing the hexagon into 6 equilateral triangles, each one will have 15-ft sides. Now divide one of these triangles in half to make a right triangle with on…e leg 7.5ft and the hypotenuse 15ft. The other leg will be the altitude of the triangle. (sorry it's hard to explain without being able to draw a diagram) Call that second side h; h2 = 152-7.52 = 225-56.25 = 168.75. h = radical 168.75 = about 12.99. The area of one equilateral triangle = (1/2)bh = (1/2)x15x12.99 = about 97.4 Area of the hexagon = 6x97.4 = approx 585.
with base dimensions 12 x 16 square footage is 12 x 16 = 192 sq ft. If you mean cubic feet it is 12 x 16 x 12 = 2304 cu ft
