We have given each square is of unit length, where length = 10 units and breadth = 6 units
(a) Perimeter of ABCD = 2 (length + breadth)
= 2(10 + 6) units
= 2 × 16 units = 32 units
(b) Area of ABCD = length × breadth
= (10 × 6) sq units = 60 sq units
(c) Since, there are several ways to divide this rectangle into 10 parts, from which one of the ways is shown below :
So, the above figure shows that there are 10 part$ of equal area i.e., E, F, G, H, I, J, K, L, M and N.
(d) The perimeter of each part is 12 units. Yes, the perimeter of each part is equal.
