Question 1
1 / -0

How many squares are there in the given figure?

A
5

B
6

C
7

D
4

Solution

The squares formed are 12, 34, 56, 78, 2367 and 12345678 i.e., 6 in number.
Question 2
1 / -0

Find the length of GH.

A
6 cm

B
3 cm

C
9 cm

D
2 cm

Solution

We have,
AB + GH + CD = FE
⇒ 3 cm + GH + 6 cm = 12 cm
⇒ GH = 12 cm - 9 cm = 3 cm
Question 3
1 / -0

Which of the following figures has the highest perimeter?

A
I

B
II

C
III

D
Can't be determined

Solution

Perimeter of a figure is the sum of all of its sides.
Perimeter of I = 5 + 2 + 5 + 2 = 14cm Perimeter of II = 2 + 2 + 2 = 6cm
Perimeter of III = 4 + 4 + 4 + 4 = 16cm Hence III has highest perimeter,
Question 4
1 / -0

Which line in the diagram is the correct line of symmetry?

A
AB

B
CD

C
EF

D
GH

Solution

GH symmetrically divides the figure.
Question 5
1 / -0

IJKL and MNOP are two rectangles. Find the length of KP.

A
3 cm

B
5 cm

C
8 cm

D
9 cm

Solution

In rectangle IJKL, we have
IJ = LM + MK (opposite sides are equal in a rectangle.) ⇒8=5+MK
∴ MK = 3 cm
In rectangle MNOP, we have
MP = NO ⇒ MK + KP = NO
⇒ 3 + KP = 12
⇒ KP = 9 cm.
Question 6
1 / -0

Line m and four points are shown on the grid. Which two points appear to lie on the same line that is similar to line m?

A
G and D

B
D and E

C
G and E

D
F and D

Solution

Points G and E appear to lie on the same line that is similar to line m.
Question 7
1 / -0

The cube shown here was cut into three pieces- Which of the following groups CANNOT be the three pieces of the cube?

A

B

C

D

Solution

Among all the given options, option [C] cannot be the three pieces of the cube.
Question 8
1 / -0

The perimeters of square P and rectangle Q are equal. Find the breadth of rectangle Q.

A
6 cm

B
8 cm

C
4 cm

D
2 cm

Solution

Perimeter of square P = 4 ×side = 4×6=24cm Perimeter of rectangle Q = 2 (Length + Breadth)
= 2 (8 + Breadth)

We are given Perimeter of P = Perimeter of Q ⇒24 = 2(8 + Breadth)

⇒24=16+2 ×Breadth

⇒2 × Breadth = 8

⇒Breadth = 4 cm
Question 9
1 / -0

Veer plotted 3 points on a grid line. The three points together make a ______.

A
Straight line

B
Square

C
Triangle

D
None of these

Solution

The three points will form a straight line.
