Question: 1
Find the largest size of a bamboo that can be placed in a square of area 100 sq. m.
(A) 10.10 m
(B) 12.12 m
(C) 14.14 m
(D) 16.16 m
Ans: C
Side of the square = $$√100$$ m = 10 m.
Largest size of bamboo = Length of diagonal of the square
= 10× $$√ 2$$ m = (10 × 1.414) m = 14.14 m.
Question: 2
The perimeter of a rhombus is 56 m and its height is 5 m. Its area is
(A) 64 sq. m
(B) 67 sq. m
(C) 70 sq. m
(D) 78 sq. m
Ans: C
Perimeter of the rhombus = 56 m.
Each side of rhombus = $${56}/{4}$$ m = 14 m.
Height of the rhombus = 5 m.
∴ Area = (14 × 5) m2 = 70 m2.
Question: 3
Area of a rectangle is equal to the area of a circle whose radius is 14 cm. If the breadth of the rectangle is 22 cm, what is its length?
(A) 22 cm
(B) 24 cm
(C) 26 cm
(D) 28 cm
Ans: D
Area of circle = $$({22}/{7} × 14 × 14)$$ cm2 = 616 cm2.
Let the length of the rectangle be l cm.
Then 22l = 616 ⇒ l = $${616} / {22}$$ = 28 cm.
Question: 4
The perimeter of a square is equal to twice the perimeter of a rectangle of length 8 cm and breadth 7 cm. What is the circumference of a semi-circle whose diameter is equal to the side of the square?
(A) 20.57 cm
(B) 23.57 cm
(C) 38.57 cm
(D) 42.46 cm
Ans: A
Perimeter of rectangle = [2(8 + 7)] cm = 30 cm.
Perimeter of square = (2 × 30) cm = 60 cm.
Side of the square = $$({60}/{4})$$ cm = 15 cm.
Radius of the semicircle = $$({15}/{2})$$ cm.
Circumference = $$({22/7} × {15/2})$$ cm = $$({165}/{7})$$ cm = 23.57 cm.
Question: 5
The number of marble slabs of size 20 cm × 30 cm required to pave the floor of a square room of side 3 metres is
(A) 150
(B) 200
(C) 250
(D) 350
Ans: A
Number of marbles = $$({300 × 300}/{20 × 30})$$ = 150.
