Answer:
The width of the rectangular frame (w) = 24.5 cm
The length of the rectangular frame (l) = 36.6 cm
The width of the border of the rectangular frame = 3.4 cm
Therefore,
The width of the picture will be = 24.5 - (2 × 3.4) = 24.5 - 6.8 = 17.7 cm
and
The length of the picture will be = 36.6 - (2 × 3.4) = 36.6 - 6.8 = 29.8 cm
Now, by using the above formula for the perimeter of a rectangle, we get
The perimeter of the picture is,
= Perimeter of a rectangle
= 2 [length + width]
= 2[29.8 + 17.7]
= (47.52×47.5)
= 95cm
Thus, the perimeter of the picture is 95 cm.
