The table shows the area of various lakes in Texas rounded to the nearest tenth. if the average area is 45.97 square miles, what is the approximate area of lake palestine

The approximate area of lake Palestine is 39.92 square miles.

Solution:

Average area = 45.97 square miles

Let x be the area of lake Palestine.

Sum of all the lakes = 43.3 + 18.7 + 70.3 + 101.4 + 2.2 + x

                                 = 235.9 + x

Number of lakes = 6

Multiply by 6 on both sides, we get

235.9 + x = 275.82

Subtract 235.9 on both sides.

235.9 + x - 235.9 = 275.82 - 235.9

x = 39.92

The approximate area of lake Palestine is 39.92 square miles.
