Answer
(i) The perimeter of a closed plane figure is the length of its boundary.
(ii) The unit of measurement of perimeter is same as that of length.
(iii) Since a rhombus has 4 equal sides, perimeter = 4 × side = 4 × 7 = 28 cm.
If the side of a rhombus is 7 cm then its perimeter is 28 cm.
(iv) The area of a closed plane figure is measured in square units (sq. units).
