Answer :
The rectangular frame of a picture is 24.5 cm wide and 36.6 cm high. The border is 3.4 cm wide. The perimeter of the picture is 149.4 cm.
- To calculate the perimeter of the picture, we need to find the lengths of all four sides of the rectangular frame. The width of the frame is given as 24.5 cm. The height of the frame is given as 36.6 cm. The border width is given as 3.4 cm.
- So, the length of the top and bottom sides of the frame would be the total width of the frame plus the twice the border width: 24.5 cm + 3.4 cm + 3.4 cm = 31.3 cm.
- The length of the left and right sides of the frame would be the total height of the frame plus twice the border width: 36.6 cm + 3.4 cm + 3.4 cm = 43.4 cm.
- Finally, the perimeter of the picture would be the sum of all four side lengths: 31.3 cm + 31.3 cm + 43.4 cm + 43.4 cm = 149.4 cm.
