3+4 = 7
so
21 / 7 3
3 x 3 = 9
3 x 4 = 12
answer
£21 in ratio 3:4 is £9:£12

I did it on paper just now. Sorry for the sloppy handwriting, but you should be able to answer the two questions with the info I got. If you don't know what five number summary is, just google it.
Basically, arrange the list of numbers in order, and then find the minimum, 1st quartile, median, 3rd quartile, and maximum.
A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles. To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.
Answer:
Thus, it is possible to erect a pole at a point p on the boundary of the park at distances 5m and 12m respectively from gates B and A.
Step-by-step explanation:
Let P be the required location of pole .
A and B are the two gates.
Let the distance of pole at p from gate be 'x' meters
i.e. PB = x m
•°• AP = (x + 7)m and AB = 13 m
•°• AP² + BP² = AB² => (x +7)² + x =13²
Rejecting x =-12, we get x = 5
•°• PB = 5m
and
AP = 12m
(I hope this helped :)
