The perimeter of a rectangle can be calculated by adding up the lengths of all its sides. In this case, the rectangle is 7 inches by 8 inches, so its perimeter would be 2(7) + 2(8) = 14 + 16 = 30 inches.
perimeter = 2(length X width) = 2(l x w) = 2(w+7+w) - 2(2w+7)=142 2w+7 = 71; 2w=64; w = 32 and l = w+7 = 39 Check: perimeter = 2(32+37) = 142
Perimeter of rectangle = 2 x (length + width) = 2 x (1.6 + 0.8) = 2 x 2.4 = 4.8 meters
perimeter of rectangle=2(l+b) l=length of the rectangle b=breadth of the rectangle
Perimeter = 2*(L+W) = 2*(3+7) = 2*10 = 20 yards. By the way, conventionally, the length is the bigger dimension.
