Accepted Solution
A:
in rectangles, opposite sides are equal. lets name the length as x as stated in the question, width is 7 less than the length therefore length is --> x-7 perimeter = 2*(length) + 2(width) substituting length and width perimeter = 2x +2(x-7) as the perimeter given is 50 inches 70 = 2x + 2x - 14 4x = 84 x = 21 inches length of tablet - 21 inches width of tablet - 14 inches
