Question

7The length and breadth of a rectangle are 12 CM and 8 CM find its area and perimeter

Answer 1

Hi Mate!!

it's area is = 12 × 8 = 96cm²

and

it's perimeter is = 2 ( 12 + 8 ) = 40cm


have a nice day ahead

Answer 2

Answer

$\ {96cm}^{2}$, 40cm

Solution

in the questions given , the length of rectangle is 12cm. and breadth of rectangle is 8cm.

Here , we find the

Area of rectangle =?

Perimeter of rectangle =?

Using formula

Area of rectangle = length × breadth

Perimeter of rectangle = 2 ( l + b )

Now we putting the value in those formula.

Area of rectangle = length × breadth

$= 12cm \times 8cm \\ \\ = {96cm}^{2}$

$We \: find \: here \: area \: \\ of \: rectangle = {96cm}^{2}$

Again we find the Perimeter of the Rectangle = 2 ( l + b )

Now putting the values in formula , where length is 12cm and breadth is 8cm.

Perimeter of rectangle = 2 ( l + b )

= 2 ( 12 cm + 8 cm )

= 2 ( 20cm)

= 40cm

$Therefore \: the \: area \: of \\ \: rectangle \: is = \ {96cm}^{2} . \\ and \: perimeter \: of \: rectangle \: \\ 40cm.$
