336 centimeters
Assuming the shape is a 3cm x 8cm rectangle, the area of this shape will be 3 x 8 = 24 cm2 - or 24 square centimetres.
there are too many dimensions for me to hazard a guess at the shape of it.
It depends on the exact configuration of the shape.
Assuming that the 3 lengths refer to the sides of a triangular shape, the area is 21.331 cm2
The perimeter would be 26cm.
Area = 1/2*(14+12)*8 = 104 square cm
Area = Base * vertical height = 8*14 = 112 cm2
If the shape measuring 8 centimeters by 5 centimeters is a rectangle, the perimeter of the rectangle is 25 centimeters (2w + 2l)
2 x (8 + 3) ie 22cm
The answer is 28 cm.
Yes, the picture frame can be reduced to 6 centimeters by 4 centimeters without distorting the shape. Both the original and reduced dimensions have the same aspect ratio (4:3), so the proportions will remain the same.
