Answer 2

The area of the largest portrait that can be put inside the frame is 10000 sq.cm.

Step-by-step explanation:

We are given that The cost of gold plating a square photo frame along the sides is ₹20000 at ₹50 per cm.

So, Perimeter of square photo frame =$\frac{20000}{50}=400$

Perimeter of square = $4 \times side$

So,$4 \times Side = 400$

$Side = \frac{400}{4} = 100$

Area of the largest portrait that can be put inside the frame = $Side^2 = 100^2 = 10000 cm^2$

Hence The area of the largest portrait that can be put inside the frame is 10000 sq.cm.
