Question 1
1 / -0

The length of the wooden strip required to frame a photograph of length and breadth 39.5 cm and 31 cm respectively, is

A
79 cm

B
1224.5 cm

C
141 cm

D
70.5 cm

Solution

Length of photograph = 39.5 cm Breadth of photograph = 31 cm ∴ Required length of the wooden strip = Perimeter of photograph = 2(39.5 + 31) = 2(70.5) = 141 cm
Question 2
1 / -0

The area of a rectangular park is 3100 m2and its breadth is 50 m. The value of 4 times its perimeter is ________.

A
896 m

B
912 m

C
825 m

D
756 m

Solution

Let the length be x m. Breadth = 50 m Now, area = 3100 m² ⇒ x × 50 = 3100 ⇒ x = 3100/50 = 62 ∴ Length = 62 m Perimeter = 2(62 + 50) = 224 m 4 times the perimeter = (4 × 224) m = 896 m
Question 3
1 / -0

80 students of the same height, stand with both hands stretched all along the sides of a rectangular garden, each student covering a length of 1.75 m. Then the perimeter of the garden is

A
1400 m

B
140 m

C
14 m

D
1400 km

Solution

Distance covered by 1 student = 1.75 m ∴ Distance covered by 80 students =(1.75 × 80) m =140 m ∴ Perimeter of the garden = 140 m
Question 4
1 / -0

If the area of the rectangle is 16 m², then which of the following may not be the possible dimensions for rectangle?

A
Length = 8m, breadth = 2 m

B
Length = 16m, breadth = 1 m

C
Length = 32 m, breadth =1/2m

D
Length = 8.5 m, breadth = 2 m

Solution

For length = 8.5 m and breadth = 2 m Area =l × b = 8.5 × 2 = 17m²≠ 16m²
Question 5
1 / -0

If side of a square is doubled, then the new perimeter is _______ times the original perimeter.

A
2

B
1/4

C
9

D
4

Solution

Let the side of square be x units. ∴ Perimeter = 4x units New side of square = 2x units ∴ New perimeter =4 × 2x = 8x units =2×4x = 2x original perimeter
Question 6
1 / -0

If perimeter of an equilateral triangle is 18 cm, then the length of its side will be________.

A
5 cm

B
6 cm

C
7 cm

D
8 cm

Solution

Given that perimeter of equilateral triangle = 18 cm ⇒ 3a = 18⇒ a = 6 ∴ Length of the side of equilateral triangle = 6 cm
Question 7
1 / -0

A figure is formed by putting two squares one on the other as shown in the figure. If the length of each side of the two squares is 8 cm, then the perimeter of the figure formed is ________.

A
56 cm

B
64 cm

C
32 cm

D
48 cm

Solution

Perimeter of figure = 2 (16 + 8) = 48 cm
Question 8
1 / -0

Find the number of envelopes that can be made out of a sheet of paper 384 cm by 172 cm, if each envelope requires a piece of paper of size 16 cm by 12 cm.

A
340

B
344

C
338

D
342

Solution

Area of sheet = (384 × 172) cm² = 66048 cm² Area of paper for 1 envelope = (16 × 12) cm²= 192 cm² ∴ Number of envelopes can be made =66048/192 = 344
