Question

Lenght =12 cm
Breadth =4 cm
Find the perimeter of area

Answer 1

Answer:

( i ) 32 cm

( ii ) 48 cm^2

Step-by-step explanation:

Given,

Length ( l ) = 12 cm

Breadth ( b ) = 4 cm

To find :

( i ) Perimeter ( rectangle )

( ii ) Area ( rectangle )

( i )

Formula : -

Perimeter ( rectangle ) = 2 ( l + b )

Perimeter ( rectangle )

= 2 ( 12 + 4 )

= 2 ( 16 )

= 32 cm

( ii )

Formula : -

Area ( rectangle ) = l x b

Area ( rectangle )

= 12 x 4

= 48 cm^2

Answer 2

CORRECT QUESTION:-

Length and breadth are 12cm and 4 cm, find the area and Perimeter of rectangle.

$\rule{250}{2}$

SOLUTION:-

Area and perimeter of rectangle can be easily find by substituting value of length and breadth in the formula.

$\rule{250}{2}$

★Area of rectangle=Length×Breadth

=>  12cm×4cm

=>   48cm²

$\rule{250}{2}$

★Perimeter of rectangle=2(L+B)

=>   2(12+4)

=>   2(16)

=>   32cm

∴ The required area and Perimeter of rectangle are 48cm² and 32cm respectively.
