To get the area of a triangle you use the equation A=1/2bh so 1/2 x 7 x 8= 28 square meters.
Using the mean concept, the expression that gives the average of the low and high temperatures is:
(-3 + 8)/2.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the two observations are -3 and 8, hence their average is given by:
(-3 + 8)/2.

Correct option is B, Lines 39-42 ("Normally . . . community")
The "matter of urgency," as Akira explains in lines 39–42, is that he has "an opportunity to go to America, as dentist for Seattle's Japanese community." Chie's response to Akira's marriage proposal is necessary for him to determine whether or not to take the position in Seattle.
The answers to the previous question are not well supported by the evidence in Choices A, C, and D. Choice A is wrong since Akira apologizes for disturbing Chie's peaceful evening in line 39. Lines 58–59 discuss the gravity of Akira's demand, not its immediacy, hence option C is incorrect.
Line 73 merely demonstrates that Akira's suggestion "startled" Chie, not why his request is time-sensitive, hence option D is incorrect.
Here's another question with an answer similar to this Chie and Akira:
