I have four sides all of 3 cm.

If it was a square, the answer would be 81 square cm. The area will be the product of two numbers whose sum is half the perimeter.
Well honey, 2 half centimeters is 10 millimeters and 7 half centimeters is 35 millimeters. So, if you add those together, you get a grand total of 45 millimeters. Math doesn't have to be boring, darling!
first convert m to cm .1 meter =100 cm now adding 100 cm and 50 cm,we get .150 cm is the sum.

No, half a decimeter is 5 cm. Decimeter is equal to 10 cm, so half of it would be 5 cm.
20 and a half cm.
half of 54.5 inches in cm? 27.25 inches in cm? 1 cm = 2.54 inches; ? cm = 27.25 inches; cross multiply 27.25incm=?2.54incm; 27.25incm/2.54in=?cm ~10.73 cm
Perimeter of Rectangle = 2(length + width) =2(45+30) =150 cm
The perimeter of a triangle is the sum of its 3 sides.
The first step in answering this question is to convert the metres value into cm. That makes the sum easier, and allows us to work with consistent units. There are 100cm in a m, so to convert from m to cm you have to multiply by 100. In this case, we have 0.5m, so multiply that by 100 to give 50cm. Therefore the question can be rewritten as how many cm is 50cm longer than 34cm. The answer is just 50-34 or 16cm.
