Answer:
length = 47 inches , width = 20 cm
Explanation:
the perimeter (P) of a rectangle is calculated as
P = 2(length + width)
let the width be w the length is 7 more than double the width , 2w + 7
given P = 134 inches
substitute these values into the formula for P
134 = 2(2w + 7 + w) ← divide both sides by 2
67 = 2w + 7 + w
67 = 3w + 7 ( subtract 7 from both sides )
60 = 3w ( divide both sides by 3 )
20 = w
and length = 2w + 7 = 2(20) + 7 = 40 + 7 = 47
dimensions are , length = 47 inches and width = 20 inches
