Question

The area of a rectangle is length X breadth. If the length of rectangle is 7.8 cm and it's breadth is 5.4 cm. Find it area in sq.cm.

Answer 1

$\sf \: Answer :$

• 42.12 sq.cm

Given :

• Length of the rectangle = 7.8 cm
• Breadth of the rectangle = 5.4 cm

To find :

• the area of the rectangle

Solution :

➝ Let's find the area of the rectangle.

→ Area of a Rectangle = l × b

Here,

• L = 7.8 cm
• B = 5.4 cm

→ Area of a Rectangle = l × b

→ Area of a Rectangle = 7.8 × 5.4

→ Area of a Rectangle = 42.12

• Therefore, the Area of the rectangle is 42.12 sq.cm.

-------------

★ Area should be always expressed in square units.

Answer 2

$\underline{ \pink{ \rm GIVEN \:  \: DATA\: \: : }}$

Length of Rectangle = 7.8cm

Breadth of Rectangle = 5.4cm

$\underline{ \purple{ \rm TO  \:  \: FIND  \: \: : }}$

Area of Rectangle

$\underline{ \red{ \rm SOLUTION \: \: : }}$

by using,

$\boxed{ \boxed{ \bf{ \color{orange}{ \bf Area \: \: of \: \: Rectangle} \color{blue} = \color{green} Length \times Breadth}}}$

$\sf ⇒ \: \: 7.8 \times 5.4$

$\bf⇒ \: \: 42.12 \: \: cm²$
