Short Answer Questions Type - II:
1. Find the perimeter and area of rectangle with length 7.2 cm and breadth 4.8 cm.​

Answer 1

Given :

• Length of Rectangle = 7.2 cm
• Breadth of Rectangle = 4.8 cm

To Find :

• Area and Perimeter of Rectangle .

Solution :

For Area :

Using Formula :

$\longmapsto\tt\boxed{Area\:of\:Rectangle=length\times{breadth}}$

Putting Values :

$\longmapsto\tt{7.2\times{4.8}}$

$\longmapsto\tt\bf{34.56{cm}^{2}}$

So , The Area of Rectangle is 34.56 cm²..

Now ,

For Perimeter :

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{2(7.2+4.8)}$

$\longmapsto\tt{2(12)}$

$\longmapsto\tt\bf{24cm}$

So , The Perimeter of Rectangle is 24cm...

_______________________

• Area of Rectangle = length × breadth
• Perimeter of Rectangle = 2 (l+b)
• Diagonal of Rectangle = √(l)² + (b)²

Answer 2

✒GIVEN:

• Length of the rectangle = 7.2 cm
• Breadth of the rectangle = 4.8 cm

✒FIND:

• What is the perimeter of the rectangle = ?
• What is the area of the rectangle = ?

✒FORMULAS USED:

• Area of an rectangle = length × breadth
• Perimeter of an rectangle

=>2(length + breadth)

✒SOLUTION:

here,

we know that,

Area of rectangle = length × breadth

where,

• Length = 7.2 cm
• breadth = 4.8 cm

substituting these values in the formula

so, we get

Area of rectangle = 7.2 × 4.8

= 34.56 cm²

Thus, area of the rectangle = 34.56 cm²

now,

we know that,

Perimeter of rectangle = 2(length + breadth)

where,

• Length = 7.2 cm
• breadth = 4.8 cm

substituting these values in the formula

so, we get

Perimeter of rectangle = 2(7.2 + 4.8)

= 2(12)

= 24 cm

Thus, perimeter of the rectangle = 24 cm

Hence,

• Area of rectangle = 34.56 cm²
• Perimeter of rectangle = 24 cn
