14 x 14 = 196 13 x 13 = 169 12 x 12 = 144196
12 x 9 - 13 = 95
It depends on whether the room is 12 feet by 13 feet or 12 metres by 13 metres or 12 cubits by 13 cubits. The question does not state the units used.
169squared just means the number times itself 2 times 13 x 13 = 169For another example 12 squared is 12 x 12. The answer is 144169. 13 X 13 = 169
13 x 0 = 0 13 x 1 = 13 13 x 2 = 26 13 x 3 = 39 13 x 4 = 52 13 x 5 = 65 13 x 6 = 78 13 x 7 = 91 13 x 8 = 104 13 x 9 = 117 13 x 10 = 130 13 x 11 = 143 13 x 12 = 156 13 x 13 = 169

15 x 13 x 12 is equal to 2,340
14 x 14 = 196 13 x 13 = 169 12 x 12 = 144196
13 x 12 x 8 =1248
12*13=156
The question seems to be saying: 3X + X/4 = 12 That can be worked as follows: x/4 = 12 - 3x x = (12-3x) * 4 x = 48 - 12X x + 12x = 48 13 x = 48 x=48/13 To evaluate: 3 * 48/13 = 144/13 (48/13) / 4 = 12/13 At this point you could divide it out, or continue to work in fractions. 144/13 + 12/13 = 12 (Simplify or divide out the fractions if you wish) 11-1/13 +12/13 = 12
156 square feet
To work out the area of a room multiply the width by the length.13 feet x 12 feet equals 156 square feet.Therefore the area of a 13 x 12 room is 156 square feet.
156
(5/6) / (13/12) = (5/6) x (12/13) = (5/1) x (2/13) = 10/13
lcm(8 12 13) = 312 Using prime factorisation: 8 = 2³ 12 = 2² x 3 13 = 13 lcm = 2³ x 3 x 13 = 312
