Length of the portrait:
The given length of the portrait is 500 cm.

Breadth of the portrait:
The given breadth of the portrait is 300 cm.

Length of the frame:
To find the length of the frame required for the portrait, we need to add some additional length on all sides of the portrait. This is done to ensure that the frame covers the entire portrait.

Addition on the length:
Let's assume that we need to add x cm on both sides of the portrait.

So, the total length of the frame will be:
Length of the portrait + Addition on the length = 500 cm + x cm + x cm

Breadth of the frame:
Similarly, we need to add some additional breadth on all sides of the portrait to find the breadth of the frame.

Addition on the breadth:
Let's assume that we need to add y cm on both sides of the portrait.

So, the total breadth of the frame will be:
Breadth of the portrait + Addition on the breadth = 300 cm + y cm + y cm

Total length of the frame:
The total length of the frame will be the sum of the length of the portrait and the additional length on both sides.

Total length of the frame = Length of the portrait + Addition on the length + Addition on the length = 500 cm + x cm + x cm

Total breadth of the frame:
The total breadth of the frame will be the sum of the breadth of the portrait and the additional breadth on both sides.

Total breadth of the frame = Breadth of the portrait + Addition on the breadth + Addition on the breadth = 300 cm + y cm + y cm

Answer:
So, the length of the frame required for a portrait of length 500 cm and breadth 300 cm is 500 cm + x cm + x cm (length) and 300 cm + y cm + y cm (breadth).

Find the length of frame required for a portrait of length 500 cm and breadth 300 cm. Also find total cost of frame, if 1 cm frame costs ₹6.
