Question

the rectangular frame of a picture is 24.5 cm wide and 36.6 cm high the border is 3.4 cm wide . calculate the perimeter of the picture​

Answer 1

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.
