I don't think you can guess that. If it was square it would be easy. But to find a perimeter its adding up all the sides. For it to be a rectangle you have to have 2 sets of sides that are equal to each other. So a possible answer could be 10
28 cm
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has two sides that are 4 feet long and two sides that are 10 feet long. To find the perimeter, you add 4 + 4 + 10 + 10, which equals 28 feet. Therefore, the perimeter of a 4 ft by 10 ft rectangle is 28 feet.

if the rectangle is 3 wide, then u subtract 3 twice from the perimeter 28. then you divide by 2 to get the length of one side of the rectangle: 28-3= 25-3= 22/2= 11 or 28-6= 22 22/2=11 so the answer is 11

Perimeter = 154 mm = 15.4 cmArea = 1,372 mm2 = 13.72 cm2
This is so simple: 2 x (28 + 15) = 86 cm.
