Question

Find area and perimeter of a rectangle of length 10 cm and width 4 cm​

Answer 1

Given:-

• Length of a rectangle is 10 cm.
• Breadth of a rectangle is 4 cm.

⠀

To find:-

• Area and perimeter of a rectangle.

⠀

Solution:-

Here,

• Length (l) = 10 cm
• Breadth (b) = 4 cm

⠀

Firstly,

• finding the area of a rectangle.

⠀

★Formula used:-

Area of rectangle = length × breadth

⠀

→ A = l × b

→ A = 10 × 4

→ A = 40 cm²

⠀

Hence,

• the area of a rectangle is 40 cm².

⠀

Now,

• finding the perimeter of a rectangle.

⠀

★Formula used:-

Perimeter of rectangle = 2(length + breadth)

⠀

→ P = 2(l + b)

→ P = 2(10 + 4)

→ P = 2(14)

→ P = 28 cm

⠀

Hence,

• the perimeter of a rectangle is 28 cm.

⠀

Therefore,

• Area (A) = 40 cm²
• Perimeter (P) = 28 cm

Find the area and perimeter of a rectangle of length 10cm and breadth 4cm.

$\huge{\color{lightgreen}{\boxed{\color{lightblue}{\sf{ANSWER:-}}}}}$

Length given = 10cm

Breadth given = 4cm

❄️ Perimeter of a rectangle = 2×(Length × Breadth)

==> 2×(10cm+4cm)

==> 2×(14cm)

==> 28cm

❄️ Area of a rectangle = Length × Breadth

==> 10cm × 4cm

==> 40cm²

❄️ Therefore, the area and perimeter of a rectangle whose length and breadth are 10cm and 4cm are 28cm and 40cm² respectively.
