Answer Key with Explanations
(C) 102 sq cm — Area = l × b = 17 × 6 = 102 sq cm.
(B) 36 m — Perimeter = 2(l + b) = 2(12 + 6) = 36 m.
(A) 72 sq cm — Area = ½ × base × height = ½ × 16 × 9 = 72 sq cm.
(C) ₹650 — Perimeter = 130 m; cost = 130 × 5 = ₹650.
(D) 169 sq cm — Area = l × b = 13 × 13 = 169 sq cm.
(A) 34 m — Perimeter = 2(l + b) = 2(10 + 7) = 34 m.
(B) 30 sq cm — Area = ½ × base × height = ½ × 10 × 6 = 30 sq cm.
(D) ₹1200 — Perimeter = 100 m; cost = 100 × 12 = ₹1200.
(C) 195 sq cm — Area = l × b = 15 × 13 = 195 sq cm.
(D) 58 m — Perimeter = 2(l + b) = 2(10 + 19) = 58 m.
