S_1 = \frac{a+b}{2}h = \frac{7+9}{2}*5=\frac{18*5}{2}= 9 * 5 = 45~m^2

S_\triangle = \frac{ab}{2} = \frac{5*9}{2} = \frac{45}{2} = 22,5~m^2

S = S_1 + S_\triangle = 45 + 22,5 = 67,5~m^2

Answer: 67,5 m².

How many dozen donuts are there in 46.2 donuts
m_a_m_a [10]
Hello there! We can answer through division here, given there are 12 donuts in a dozen:

46.2 divided by 12 gives us 3.85 dozens. However, there cannot be a fraction of a dozen in representation of a whole. Rounding to the nearest dozen, we will find that there are about 4 dozens in 46.2 donuts.

For there to be a value of 46.2 donuts, there had to have been more donuts to start with in the dozen. Therefore, we would round up. If there were 3 dozens, that would give us 36 donuts, which would not make sense because there are 46.2 present.

Hope this helps!
