Based on the above, the Perimeter of shape B is known to be 50 cm
What is the Perimeter of the shape?
The perimeter of a shape is the total length of its boundary or the sum of all its sides. The formula for calculating the perimeter varies depending on the shape.
Perimeter of shape A = 60 cm
Let the length of each square = x cm
Total length of free boundaries of shape A = 12x
So , 12x = 60
x = 5 cm
Now length surfaces of shape B = 10x
Perimeter of shape B = 10x
= 10(5)
= 50 cm
