Answer 1

Your answer is here buddy:)

The length of wodden frame required = perimeter of the picture.

As we know that the picture is in the form of a rectangle, we will apply the formula for finding the perimeter of a rectangle here;

Perimeter of rectangle = 2(L+B).

L= 30cm & B= 20cm.

So,

Perimeter of rectangle = 2(30cm+20cm).

= 2×50cm.

= 100cm.

Hence, the length of the required wooden frame is 100cm.

Hope it helps you.

Please mark as brainliest. :)
