A rectangular piece of paper has a width that is three inches less than it’s length. It is cut in half along a diagonal to create two congruent right triangles with areas of 44 square inches.

(Measure ) L+W :  11 and 8 inches.

These L + W measures are of each triangle and when either halved as proven below will show (A): 44inch^2

Step-by-step explanation:

Two congruent triangles of 44 sq inch = base 8  height  11  

or base 11 height 8

Finding that both numbers find the same area.

Note for future areas either measure for triangle base + height

8 x 11 or 11 x 8 = 88  when halved its the same answer.  

where 7 x 10 = 35

13 x 10 = 65

and so on;

No other number multiplies its length and height to show 44

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.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
