A) 59% B) 69% C) 49% D) 89%
6. What is the radius of a circular field of area 5566 m2?
A) 42.08 m B) 43.8 m C) 52.9 m D) 61.4 m
7. The perimeter of the rectangular field of length 156 m and breadth 72 m is....
A) 325 m B) 356 m C) 425 m D) 456 m
Sol: Perimeter of rectangular field = 2(156 + 72) = 2(228) = 456
Ans: D
9. The diagonal of square A whose perimeter is 60 is equal to the side of square B. What is the area of square B?
A) 640 B) 280 C) 360 D) 450
Sol: Perimeter of square A = 60
4a = 60
a = 15
10. What is the area of trapezium with parallel sides having the lengths 14 m and 18 m. The perpendicular distance between them is 15 m?
12. The perimeter of a equate is 340 cm. Find its area.
17. The ratio of length and breadth of a rectangle is 6 : 5 respectively. If the breadth is 72 cm less than the length, what s the perimeter of the rectangle?
A) 1584 cm B) 1112 cm C) 1235 cm D) 2436 cm
Sol: Let length and breadth be 6x and 5x respectively
6x − 5x = 72 ⇒ x = 72
Perimeter of rectangle = 2(l + b)
= 2(6x + 5x)
= 2(11x) = 22x
= 22(72) = 1584 cm
Ans: A
