The length of a rectangle is 5 centimeters less than twice its width . the perimeter of the rectangle is 80 cm what
are the dimensions of the rectangle

a length = 25cm; width = 15cm
b length = 22cm; width = 18cm
c length = 23cm; width = 14cm
d length = 24cm; width= 16cm

B) is the answer because 22+22+18+18 will equal 80 and 22-18 is five

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

the workers who do no drive has no reasonable reason to buy gasoline due to they don't have anything to use it for
