Three towns P, Q and R are such that P is on a bearing of 120° and 20km from Q. Town R is on a bearing of 220° and 12km from P hence a)Using a scale of 1cm to2km, draw and locate the positions of the three towns. b) Measure: i) the distance between Q and R in Kilometres. ii) the bearing of P from R. iii) the bearing of R from Q. c) Calculate the area of the figure bounded by PQR.​

Step-by-step explanation:

i think that you should ask google for the answer to that problem because if we don't know it google does

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
