Find the perimeter and area of a rectangle with the following length and breadth: i. L = 10.5m, B = 5.5m
ii. L = 15cm B = 6.8cm

perimeter: 2(l+b) , area : multiply by breadth

Step-by-step explanation:

perimeter: 2(10.5+5.5)

               :206.5m ans

area: 10.5multiply bye 5.5

      :57.75m ans

2: perimeter: 2(15+6.8)

                   : 36.8cm ans

area : 15 multiply by 6.8

        : 102cm ans  

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
