2*(base) + 2*(height) = perimeter

If you mean a 3 inches by 4 inches rectangle then its perimeter is 14 inches

all you have to do is add together the four sides. 2L+2W=Perimeter (L=length or base, W=Width or height)

3+3+7+7 = 20 inches

44.3 mm

all you have to do is add together the four sides. 2L+2W=Perimeter (L=length or base, W=Width or height)

Height works out as: 33.7 mm Check: 2*(33.7+71.4) = 210.2 which is the perimeter

Assuming that this question should have read, "The perimeter of a rectangle is 38m. The base is four more than two times the height. What is the height?", the answer can be obtained as follows: The perimeter of a rectangle is the twice the sum of its base and height. Call the unknown height h. Then, from the problem statement, 2[h + (2h + 4)] = 38. Expanding and collecting like terms gives 6h = 30 or h = 5 m.
