Question

The side of square is 4 cm The length of a rectangle is 8 cm and its width is 2 cm find the perimeter and area of both figure​

Answer 1

☆ Square ☆

Given:

• Side of the square = 4 cm

To find:

• Area and perimeter of square

Solution:

We know that,

$\boxed {\mathfrak {\orange {Perimeter\ of\ square = 4s}}}$

Where,

s denotes side of the square.

Perimeter = 4×4

$\bigstar {\bf {\pink {Perimeter\ of\ square = 16\ cm}}}$

Now,

$\boxed {\mathfrak {\green {Area\ of\ square = s^{2}}}}$

Area = 4²

$\bigstar {\bf {\pink {Area\ of\ square = 16\ cm^{2}}}}$

Area and Perimeter:

Area of the square is 16 cm² and perimeter of the square is 16 cm.

☆ Rectangle ☆

Given:

• Length of the rectangle = 8 cm
• Breadth of rectangle = 2 cm

To find:

• Area and perimeter of rectangle.

Solution:

We know that,

$\boxed {\mathfrak {\blue {Perimeter\ of\ rectangle = 2(l+b)}}}$

Where,

l denotes Length

b denotes Breadth

Perimeter = 2(8+2)

Perimeter = 2×10

$\bigstar {\bf {\pink {Perimeter\ of\ rectangle = 20\ cm}}}$

Now,

$\boxed {\mathfrak {\red {Area\ of\ rectangle = l \times b}}}$

Area = 8×2

$\bigstar {\bf {\pink {Area\ of\ rectangle = 16\ cm^{2}}}}$

Area and Perimeter:

Area of the rectangle is 16 cm² and perimeter of the rectangle is 20 cm.
