Question

if length and breadth of the rectrangle is 2.5cm and 1.8 cm then find its area and perimeter​

Answer 1

Solution

GIVEN,

Length of the rectangle ⇛ 2.5

Breadth of the rectangle ⇛ 1.8

━━━━▣━━◤◢━━▣━━━━━

To find

AREA AND PERIMETER

━━━━▣━━◤◢━━▣━━━━━

Formula

1) Area = length X breadth

2) perimeter = 1 ( length + breadth)

─━━━━━━⊱✿⊰━━━━━━─

Solving

➣ Area = length X breadth

➣ Area = 2.5 X 1.8

➣ Area = 4.5 cm²

Area 4.5 cm²

_____________(✪)___________

Perimeter = 2 ( length + breadth)

➤ perimeter = 2( 2.5 + 1.8)

➤ perimeter = 2 ( 4.3)

➤ perimeter = 8.6cm

Answer 2

☯ GIVEN :

• Length of the rectangle : 2.5 cm

• Breadth of the rectangle : 1.8 cm

☯ TO FIND :

• Area and Perimeter.

☯ FORMULA REQUIRED :

$\bigstar{\underline{\boxed{\red{\bf{{Area =Length\times Breadth }}}}}}$

$\bigstar{\underline{\boxed{\red{\bf{{Perimeter =2(Length+Breadth) }}}}}}$

☯ SOLUTION :

$\implies {\sf{Area =Length\times Breadth}}$

$\implies {\sf{Area =2.5\times1.8 }}$

$\implies { \underline{\boxed{ \red{\bf{Area =4.5 \: cm^2 }}}}}$

$\huge{\pink{\therefore}}$ Area = $\bf{4.5 \: cm^2}$

_________________________

$\implies {\sf{Perimeter =2(Length + Breadth)}}$

$\implies {\sf{ Perimeter=2(2.5 + 1.8) }}$

$\implies {\sf{ Perimeter=2 \times 4.3 }}$

$\implies { \underline{\boxed{ \pink{\bf{Perimeter =8.6 \: cm }}}}}$

$\huge{\red{\therefore}}$ Perimeter = $\bf{8.6 \: cm}$
