Answer 1

Answer:

Here you go! Your welcome!

Step-by-step explanation:

Examples of calculating perimeter and Area:

A) Rectangle:

Imagine that;

Length: 3 cm

Breadth: 2 cm

Perimeter of Rectangle: 2(length + breadth)

2 (3 + 2)

Now, according to BODMAS, we'll solve bracket first!

2 (5)

2 × 5 = 10 cm = Perimeter!

Area of rectangle: Length × Breadth

3 cm × 2 cm = 6 cm = Area!

B) Square:

Imagine that;

Side: 6 cm

Perimeter of Square: 4 × side

4 × 6 cm = 24 cm = Perimeter!

Area of Square: (Side)² or side × side

6 cm × 6 cm = 36 cm = Area!

C) Circle:

Imagine that;

Radius: 7.5 cm

Perimeter of Circle: 2πr

2πr = 2 × 22/7 × 75/10 = 47.7 cm = Perimeter!

Area of Circle: πr²

πr² = 22/7 × (7.5)² = 22/7 × 7.5 × 7.5 = 176.71459 cm = Area!
