Question

1Q)Find the Perimeter and Area of a rectangle with
length 24 cm and breadth 10 cm.​

Answer 1

Step-by-step explanation:

length of rectangle = 24 cm

breadth of rectangle = 10 cm

Perimeter of rectangle = 2( l + b)

2 ( 24 + 10 )

2 ✖ 34

68 cm

Area of rectangle = length ✖ breadth

24 ✖ 10

240 cm

Hope it is helpful

Answer 2

Given:

✰ Length = 24 cm

✰ Breadth = 10 cm

To find:

❈ Perimeter of a rectangle

❈ Area of a rectangle

Solution:

Let length of the rectangle = l cm

then, breadth = b cm

By using formula, we will calculate both the perimeter and breath of a rectangle.

Perimeter of rectangle = 2 ( l + b )

Putting the values in,

➟ Perimeter of rectangle = 2 ( 24 + 10 )

➟ Perimeter of rectangle = 2 ( 34 )

➟ Perimeter of rectangle = 2 × 34

➟ Perimeter of rectangle = 68 cm

∴ Perimeter of rectangle = 68 cm

Now, let's find out the area of rectangle....

Area of rectangle = l × b

➟ Area of rectangle = ( 24 × 10 ) cm²

➟ Area of rectangle = 240 cm²

∴ Area of rectangle = 240 cm²

Assimilate:

Perimeter:

Perimeter of a rectangle is sum of all the sides of a rectangle.

Derivation of formula:

Since perimeter equal to sum of all the sides of a rectangle....

➲ P = Sum of all the four sides

➲ P = a + b + c + d

Since, opposite sides of rectangle are equal, we have:

➲ P = a + b + a + b

➲ P = 2a + 2b

➲ P = 2 ( a + b )

Area:

Area of a rectangle is the region enclosed by all its four sides i.e., region enclosed by perimeter and is equal to product of length and breadth of rectangle.
