The formula for the perimeter is 2L + 2W.
Since we know that L=10+W, we can substitute this into the equation.
2(10+W) +2W=124
20+2W + 2W=124
4W +20 = 124
4W=104
W=26
Therefore, the width is 26 inches.
The width of the rectangular poster is 26 inches .
The poster is rectangular.
let
l = length
w = width
The perimeter of a rectangle is represented as follows:
- 2(l + w)
The length of a rectangular poster is 10 inches longer than the width. Therefore,
l = 10 + w
Perimeter = 124 inches
Therefore,
2(l + w) = 124
2(10 + w + w) = 124
2(10 + 2w) = 124
20 + 4w = 124
4w = 124 - 20
4w = 104
w = 104 /4
w = 26
Therefore, the width of the rectangular poster is 26 inches.
