Answer:
Sara- 17
Mark- 51
Caroline- 34
Step-by-step explanation:
1) start by adding the ratios together, so 1+3+2= 6. Due to the order of the ratio, Sara, gets 1 art of the money, Mark gets 3 parts and Caroline get 2 parts.
2) take the total amount of money (102) and divide it by (1+3+2). 102/6 is 17.
3) divide the money by the amount each person gets. Sara only has one part, so she has £17, Mark gets 3 parts so he gets £51, and Caroline gets 2 parts, so she ends up with £34.
4) do 17+34+51 to check it equals 102. ( it does ;D)
Perimeter of a square = 20 feet = 4a
=>4a = 20
=>a = 20/4
=>a = 5 feet
Area of a square = a²
=>a² = 5²
=>a = 25 square feet
