The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.
If it's a rectangle, 48 m.
To calculate the perimeter of a rectangle, you multiply 2 x length and add 2 x width. So the perimeter of a 3 x 5 rectangle would be: 2 x L + 2 x W (2 x 3) + (2 x 5) 6 + 10 = 16
The formula to calculate perimeter of a rectangle is P=2L+2W P= 2(15) + 2(10) P= 30 +20 P = 50
Perimeter = 2*(L+ W) = 2*(11 + 4) = 2*15 = 30 metres.
