Answer:
275 units^2
Step-by-step explanation:
The formula for the area of trapezoid is:
Area=((b1+b2)/2)*h
In the given trapezoid, as it can be seen
b1=16
h=11
The lower base will be calculated using all the lengths in the lower base
b2=9+16+9
b=34
Putting the values in formula
Area=((16+34)/2)*11
Area=(50/2)*11
Area=25*11
=275 units^2
Answer:
Let fertilizer be F
and peat moss be P
since F is proportional to P
F = kP
where, k = constant of proportionality
k = F/P
putting in the values,
k = (3/4) /12
k = 3/4 * 1/12
k = 1/16
Therefore the constant of proportionality is 1/16.

Answer:
16 cm^2 and 49 cm^2
Step-by-step explanation:
The ratio of areas is the square of the ratio of linear dimensions, so is ...
(4/7)^2 = 16/49
The sum of these "ratio units" is 16 +49 = 65. The sum of triangle areas is 65 cm^2, so each "ratio unit" must stand for 1 cm^2 of area. That is, the triangles must have areas of ...
