A.19 cm
B.38 cm
C.84 cm
D.48 cm
Show Answer+

Answer: 38 cm

Hint: Perimeter of a rectangle = 2 × (length + breadth).

Solution:

Formula for perimeter of a rectangle: — Perimeter = 2 × (l + b)

Substitute: — Perimeter = 2 × (12 + 7) = 2 × 19 = 38 cm

3What is the area of a rectangle with length 10 cm and breadth 6 cm?

A.16 cm²

Answer: 60 cm²

Hint: Area of a rectangle = length × breadth.

Solution:

Formula: — Area = length × breadth

Substitute: — Area = 10 × 6 = 60 cm²

4Find the area of a square with side 8 cm.

A.32 cm²
B.64 cm²
C.16 cm²
D.24 cm²
Show Answer+

Answer: 64 cm²

Hint: Area of a square = side × side.

Solution:

Formula: — Area = side × side = side²

Substitute: — Area = 8 × 8 = 64 cm²

5What is the perimeter of a triangle with sides 5 cm, 7 cm, and 9 cm?

A.12 cm
B.21 cm
C.35 cm
D.15 cm

A.60 cm²
B.30 cm²
C.17 cm²
D.120 cm²
Show Answer+

Answer: 30 cm²

Hint: Area of a triangle = ½ × base × height.

Solution:

Formula: — Area = ½ × base × height

Substitute: — Area = ½ × 12 × 5 = 30 cm²

7The perimeter of a square is 48 cm. What is the length of each side?

A.8 cm
B.10 cm
C.12 cm
D.16 cm
Show Answer+

Answer: 12 cm

Hint: Divide the perimeter by 4 to get each side.

Solution:

Perimeter of a square = 4 × side

So, side = Perimeter ÷ 4: — side = 48 ÷ 4 = 12 cm

8What is the perimeter of an equilateral triangle with side 11 cm?

A.22 cm
B.33 cm
C.44 cm
D.55 cm
Show Answer+

Answer: 33 cm

10The perimeter of a rectangle is 30 cm and its length is 10 cm. Find the breadth.

A.5 cm
B.10 cm
C.15 cm
D.20 cm
Show Answer+

Answer: 5 cm

Hint: Perimeter = 2(l + b). First find (l + b), then subtract the length.

Solution:

Using the perimeter formula: — 30 = 2 × (10 + b)

Divide both sides by 2: — 15 = 10 + b

Solve: — b = 15 - 10 = 5 cm
