(v) If the length of a rectangle is 5 m and its breadth is 4 m, then its area is ...... .

Answer 1

(i) A polygon having all sides equal and all angles equal is called a regular polygon
(ii) Perimeter of a square = 4 × side
(iii) Area of a rectangle = (length) × (breadth)
(iv) Area of a square = (side)²
(v) If the length of a rectangle is 5 m and its breadth is 4 m, then its area is 20 m²
Area of a rectangle = (length) × (breadth) = (5×4) m² = 20 m²
