Question

length and breadth of a rectangle are 15 cm and 9 cm then find its perimeter and area​

Answer 1

Answer:

perimeter of the rectangle = 48 cm  

Area of the rectangle = 135 cm²

Step-by-step explanation:

Length , l = 15cm

breadth , b=9cm

=> perimeter, p = 2(l+b)  units

                          = 2(15+9) cm

                          = 2(24) cm

                          = 48 cm

& Area, A = l*b sq.units

                = 15*9 cm²

                = 135 cm²

Answer 2

Answer:

• The perimeter of rectangle is 48 cm.
• The area of rectangle is 135$\rm\bold{cm^2}$.

Solution:

Given that:$\:\:\:\:\:$Length of rectangle is 15 cm and breadth of rectangle is 9 cm.

To Find:$\:\:\:\:\:$Perimeter of rectangle and area of rectangle = ?

Required Formula:

$\:\:\:\:\:$

• Perimeter of rectangle = 2(l+b)

• Area of rectangle = l × b

Step by step explanation:

$\:\:\:\:\:$

Let us find the perimeter of rectangle,

$\:\:\:\:\:$

Perimeter of rectangle = 2(l+b)

Perimeter of rectangle =2(15+9)

Perimeter of rectangle = 2(24) = 48 cm

Now, Area of rectangle,

$\:\:\:\:\:$

Area of rectangle = l × b

Area of rectangle = 15 × 9 = 135$\rm{cm^2}$
