Answer: 7.4.
Step-by-step explanation: To find the area of a triangle, you need the base, height, and then divide the results by two. The following is done below:
A = h x b / 2, where h is the height, b is the base, and A is the area of the triangle.
A = 3.7 x 4 = 14.8.
Next, 14/8 / 2 = 7.4.
Therefore, 7.4 is your answer.
Hope this helps! :)

.
Step-by-step explanation:
It is given that a number, x, rounded to 2 significant figures is 1300.
It is possible if,
1. The value of x is greater than of equal to 1250 and less than or equal to 1300.
i.e., ...(1)
2. The value of x is greater than of equal to 1300 and less than 1350.
i.e., ...(2)
On combining (1) and (2), we get
1350 is not included in the error interval for x.
Interval notation is .
Therefore, the error interval for x is .
