Question

3. The area of rectangular field is 480 m². If the breadth is 20 m. Find the perimeter of the
rectangle.​

Answer 1

Answer: 88m

Step-by-step explanation: area = 480m^2

breadth = 20m

so length = 480 / 20

= 24m

L= 24m and B = 20m

so perimeter = 2(l+b)

= 2( 24 + 20 )

= 2 * 44

= 88m

hope this helps you

Answer 2

Answer:

the perimeter of rectangle is 520m

Step-by-step explanation:

given,

area of the rectangle=480$m^{2}$

breadth=20m

length=x

AREA OF RECTANGLE=LENGHT X BREADTH

                                480     =x X 20

                                480/20=x

                                  x=24m

length=24m

perimeter of rectangle=2(l+b)

                                     =2(24+20)

                                     =2(44)  

                                     =88m
