Question

If the length and breadth of a rectangle are 12cm and 4cm respectively then find the perimeter and area of that rectangle.

Answer 1

Answer:

Preimeter of a rectangle=2×(12cm+4cm)=28cm

Answer 2

Step-by-step explanation:

$\large \underline \bold{solution : }$

Given,

Length = 12 cm

Breadth = 4 cm

$\large \underline \bold{ \: to \: find \: perimeter : }$

Formula to find the perimeter of a rectangle: 2(l+b)

$= 2(12 + 4) \: cm$

$= 2(16) \: cm$

$= 32 \: cm$

$\large \underline \bold{to \: find \: the \: area : }$

Formula to find the area of the rectangle:

l*b ( Length * Breadth )

$= 14 \times 2 \: c {m}^{2}$

$= 28 \: {cm}^{2}$

$\bold{therefore \: \: \: \: } \\ \\ \underline\bold{perimeter \: = 32 } \\ \\ \underline \bold{area =28 {cm}^{2} }$
