Solve the problem by writing an inequality. If the perimeter of a rectangular picture frame must be less than 200 in., and the width is 36 in., what must the height h of the frame be?. A. h < 64 in. . B. h > 128 in. . C. h > 64 in. . D. h < 128 in.
The perimeter of the rectangular picture frame can be calculated by the equation, 2h + 2w = P where h and w are height and width , respectively. Substituting the known values and the condition for the inequality, 2h + 2(36 in) < 200 The inequality gives h as, h < 64 Thus, the answer is letter A.
