Answer:

370

Step-by-step explanation:

Round each answer into easier to add numbers. 92 and 91 round down to 90. 9 rounds up to 10.

Answer:

aprox 280

Step-by-step explanation:

if you need to add these numbers quickly you can estimate either with an overestimation or under estimation:

for an over estimation, you can find the nearest 10 or 100 that each value is so for this you have 92 + 91 +92 +9 which is close to 100 +100+100+10

so using this you can quickly guess that it would be somewhere around 310

for an under estimation you can do the same thing but rounding down so we instead would add 90 + 90 + 90 + 10 which gives 280

now using both we know the answer would be somewhere between 280 and 310

The approximate area of the park on the grid is: E. about 40 km² to 50 km².

<h3>How to Find the Approximate Area on a Coordinate Grid?</h3>

The number of square on a coordinate grid that is covered determines the area covered. We can make an estimate by counting how many of this square on the coordinate grid that is covered, then find out the area depending on how much square area each grid represents.

In the coordinate plane given, which shows a park, we are told that each of the square on the grid equals 1 k = square kilometer.

The number of each of these squares we can find that is covered by the park on the grid is: 48 squares.

Therefore, the area of 48 squares on the grid = 48 × 1 = 48 km². Since not all squares are fully covered by the park, we can state that the approximate area of the park on the grid is: E. about 40 km² to 50 km².
