a rectangle picture 7cm by 9cm is enclosed by a frame 1\2cm wide. calculate the perimeter of the picture?
So we add 1/2 cm to each side of the picture.
length of picture = 9+.5+.5 = 10 cm
width = 7+.5+.5 = 8 cm
can you find the perimeter of this picture now?
To calculate the perimeter of the picture, we need to consider the dimensions of both the picture and the frame.
The given rectangle picture has dimensions of 7 cm by 9 cm.
The frame is 1/2 cm wide, which means it adds an extra 1/2 cm to each side of the picture. Thus, the total width of the framed picture is 7 + (1/2) + (1/2) = 8 cm, and the total height is 9 + (1/2) + (1/2) = 10 cm.
Now, to calculate the perimeter of the picture, we add up all the sides.
Since the opposite sides of a rectangle are equal, we have:
Perimeter = 2 * width + 2 * height
Plugging in the values, we get:
Perimeter = 2 * 8 cm + 2 * 10 cm
Perimeter = 16 cm + 20 cm
Perimeter = 36 cm
Therefore, the perimeter of the picture is 36 cm.
I believe we have
