Question

The length of rectangular field is 18cm and breadth of rectangular fields is 20cm . then find the perimeter of rectangular field and also area.​

Answer 1

Answer:

Perimeter = 76 cm

Area = 360 cm²

Step-by-step explanation:

Given -

Length of rectangle (l) = 18 cm

Breadth of rectangle (b) = 20 cm

To find -

The perimeter and area of rectangle

Solution -

Perimeter of rectangle = 2 × (l+b)

= 2 × (20 cm + 18 cm)

= 2 × (38 cm)

= 76 cm

Area of rectangle = l × b

= 20 cm × 18 cm

= 360 cm²

Hence perimeter of rectangle = 76 cm and area = 360 cm².

hope it helps.

Answer 2

Answer:

${ \underline{ \large{ \pmb{ \sf{Given... }}}}}$

• Length of rectangular field = 18cm
• Breadth of rectangular field = 20cm

${ \underline{ \large{ \pmb{ \sf{Find... }}}}}$

• Perimeter & Area?

${ \underline{ \large{ \pmb{ \sf{Solution... }}}}}$

Perimeter of rectangular field:-

• For Finding perimeter we use a formula by having length and breadth.

• ${ \boxed{ \sf{Perimeter = 2(l + b)}}}$

$: { \implies{ \sf{Perimeter = 2(18 + 20)}}} \\ \\ : { \implies{ \sf{Perimeter = 2(38)}}} \\ \\ { \implies{ \sf{Perimeter = 76}}}$

Area of Rectangular field:-

• We know a formula for finding a area by using length & breadth

• ${ \boxed{ \sf{Area = l \times b}}}$

$: { \implies{ \sf{Area = 18 \times 20}}} \\ \\ : { \implies{ \sf{Area = 360}}}$

Therefore,

• Perimeter = 76cm
• Area = 360cm²
