Which formula is used to determine the total number of square feet in a room?

To determine the total number of square feet in a room, the formula we should use is Area (ft2) = length x width.

Measuring the length and width of your area then multiplying those two numbers together to get the area in feet squared (ft2) is the way to calculate a rectangular area. Split it into square or rectangular sections and treat them as two separate areas if you have on oddly shaped area, such as an L-shape. Add them together for your total after calculating the area of each section. You can first convert those values to feet, then multiply them together to get the square footage of the area if your measurements are in different units, say feet and inches.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
