उत्तर
1. Perimeter of a rectangle ABCD
= 2 × length + 2 × breadth
= 2 × 3.5 + 2 × 2.5
= 7 + 5
= 12 cm
2. Perimeter of a rectangle EFGH
= 2 × length + 2 × breadth
= 2 × 3.8 + 2 × 1.3
= 7.6 + 2.6
= 10.2 cm
3. The perimeter of a Square PQRS
= 4 × length of side
= 4 × 2.4
= 9.6 cm
4. The perimeter of a rectangle STUV
= 2 × length + 2 × breadth
= 2 × 3 + 2 × 2
= 6 + 4
= 10 cm
