There are two equations and two unknowns so is easily sovled. 2b + 2h = 40 This is the perimeter equation b= 5 + 4h this is given in the statement substitute the definition of b for the first equation giving 2(5+4h) + 2h = 40 solve for h to find h=3

The perimeter of a rectangle is 38mthe base is four more than two times the heightwhat is the height?
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.
