Answer: a) P=10c b) A=4(c^2)
Step-by-step explanation:
the length of each side is c
a) the perimeter is the border of the whole shape. we can see here there are 4 squares but together. each square has 4 sides however since they are connected, we only count 10 of them for the perimeter. 4 for the top and bottom and 1 on each side (4+4+1+1)=10. so it would be 10c
b) area is width x length. which is c x c or c^2. multiply this by however many squares there are. in this case its 4. so it would be 4 x (c^2) or 4(c^2)
