I don't believe that 1 and 17/20 can be simplified any further. It is already in lowest terms.

Step-by-step explanation:
Let Julie age be x
Janet: x+3
Brother: x+8
x+x+3+x+8=55
3x+11=55
3x=44
x=14.7
Answer: 94.54 m^2 (square meters)
Step-by-step explanation: The formula for the area of a trapezoid is A = 1/2(a+b)h; where a and b are the two top sides of the trapezoid that are parallel. Let us then solve.
Let us combine both sides two maintain the overall side for "b", which is 18 + 5.1 = 23.1
Let us now add both sides (a + b.) 23.1 + 9.5 is 32.6. We can now multiply by the height. 32.6 multiplied by 5.8 is 189.08
We can now divide (or multiply by 1/2), which is 189.08 * 1/2 or 189.08/2 and that equals 94.54.
