Assuming that it is a square of 9 cm by 9 cm, the perimeter is 36 cm.
15*9 cm = 135 cm = 53.15 inches. This is NOT the same as the area of 15 cm x 9 cm since that is not what the question was about.
Area of the square: 9 times 9 = 81 square cm
A = LW A = (9 cm)(4 cm) = 36 cm^2
18
81 cm
2 * 9 cm + 2 * 4 cm = 18 cm + 8 cm = 26 cm or 9+9+4+4=26cm
9+9+9 = 27 cm
The standard size brick in India is 19 cm by 9 cm by 9 cm (As per IS recommendations).
Each centimetre equals 10 millimetres. So, 9 cm equals 90 mm.
Assuming that it is a square of 9 cm by 9 cm, the perimeter is 36 cm.
There are 100 cm in 1 meter. Therefore, 2 meters is equal to 200 cm. Adding 9 cm to this gives a total of 209 cm in 2 meters 9 cm.
About 22.86 cm
175,2 cm
10 mm = 1 cm so 9 mm = 9/10 cm = 0.9 cm. Simple!
299 cm = 9 ft 10 inches (approx).299 cm = 9 ft 10 inches (approx).299 cm = 9 ft 10 inches (approx).299 cm = 9 ft 10 inches (approx).
10 mm = 1 cm ⇒ 9 mm = 9 ÷ 10 cm = 0.9 cm
