Answer:
54m2
Step-by-step explanation:
Cut the shape into two - from the 9m length. One has 3m by 8m(ie 5m + 3m) dimensions, and the other 6m(ie 9m - 3m) by 5m dimensions.
Taking area of first one=24m2,then area of the second =30m2.
To get area of whole shape, we add both areas=54m2
NB:Area=l×b
Answer:
The triangles are congruent.
Step-by-step explanation:
The dashes represent the same size of a side.

Answer:
Year 2004
Step-by-step explanation:
Population of a country in year 1995 = 286
Model that expresses the growth rate of the population is,
P(t) = 
Here, t = year
a). For P = 311 million people
311 = 

log(311) - log(286) = (t - 1995)log(1.009)
2.4928 - 2.4564 = (t - 1995)(0.00389)

t = 1995 + 9.4
t = 2004
In year 2004 population of the country will be 311.
The answer is b, c, and d
