Can anybody help me find out how to get the other marks on this question please?

the percentage is 55/100*100=55%

Step-by-step explanation:

the segment of the square is 40/4=10 cm

so the area of the square is  10^2=100cm^2

the shaded area = the  area of the square -  the sum of the areas of  the triangles inside the square

100- (10*6/2+10*3/2)=100-(30+15)=55 cm^2

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
