Q2. A rectangular carpet has an area of 60 sq.m its diagonal and longer side together equal 5 times the shorter side. The length of the carpet is:_________?
Answer: 12m
Explanation: Testing l = 12, w = 5: area = 60 ✓, diagonal = 13, and 13 + 12 = 25 = 5 × 5 ✓; length = 12 m.
Q3. The length of a hall is (4/3) times its breadth. If the area of the hall be 300 square meters the difference between the length and breadth is__________?

Q4. A rectangular field has dimensions 25m by 15m. Two mutually perpendicular passage of 2m width have been left in it's central part and grass has been grown in rest of the field. The area under the grass is____________?
Answer: 299 m²
Explanation: Two perpendicular passages of width 2 m cover: 25×2 + 15×2 − 2×2 = 76 m²; grass area = 375 − 76 = 299 m².
Q5. A 25 cm wide path is to be made around a circular garden having a diameter of 4 meters. Approximate area of the path is square meters is__________?
Answer: 3.34
Explanation: Inner radius = 2 m, outer = 2.25 m; path area = π(2.25² − 2²) = π × 1.0625 ≈ 3.34 m².
