Question 1

What is the area of the largest circle that can fit completely inside a square of side 18 meters?

 A

81π sq. m.

 B

162π sq. m.

 C

6561π sq. m.

 D

40.5π sq. m.

Soln.
Ans: a

The radius of such a circle is 18/2 = 9 m. So its area = π × 9 × 9 = 81π sq. m.


Question 2

The diagonal and one side of a rectangle are 5 m and 3 m. What is the area of the rectangle?

 A

12 sq. m.

 B

14 sq. m.

 C

10 sq. m.

 D

16 sq. m.

Soln.
Ans: a

The side = $√{5^2 - 3^2}$ = $√{25 - 9}$ = 4. So the area = 3 × 4 = 12 sq. m.


Question 3

The difference between the length and breadth of a rectangle is 10 m. What is the area if the perimeter is 48 meters?

 A

119 sq. meters.

 B

121 sq. meters.

 C

117 sq. meters.

 D

123 sq. meters.

Soln.
Ans: a

If L and B are the length and breadth of the rectangle, then L - B = 10 and 2(L + B) = 48. Solving, we get L = 17 and B = 7, so the area is 17 × 7 = 119 sq. m. TIP: Sometimes long multiplications can be avoided by looking at the units place of the given options.


Question 4

The diagonal and one side of a rectangle are 34 m and 16 m. What is the area of the rectangle?

 A

480 sq. m.

 B

482 sq. m.

 C

478 sq. m.

 D

484 sq. m.

Soln.
Ans: a

The side = $√{34^2 - 16^2}$ = $√{1156 - 256}$ = 30. So the area = 16 × 30 = 480 sq. m.


Question 5

The diagonal and one side of a rectangle are 26 m and 24 m. What is the area of the rectangle?

 A

240 sq. m.

 B

242 sq. m.

 C

238 sq. m.

 D

244 sq. m.

Soln.
Ans: a

The side = $√{26^2 - 24^2}$ = $√{676 - 576}$ = 10. So the area = 24 × 10 = 240 sq. m.
