Answer:
length of rectangle = 8 c.m.
Step-by-step explanation:
side of square = 6 c.m.
width or breadth of rectangle = 4 c.m.
and given that, perimeter of square = perimeter of rectangle
perimeter of square = 4×side = 4 × 6 c.m. = 24 c.m.
perimeter of rectangle = 2(l + b) = 2×l + 2×4=2×l + 8
⇒24 c.m = 2×l + 8
=16 c.m. = 2×l
⇒l = 16÷2 c.m.
=8 c.m.
