Q:
# a jumbo tablet in the shape of a rectangle has a perimeter of 50 inches. The tablet is 7 inches less wide than it is long. find the length and width of the tablet. help plzz

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

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
