Answer:
7.5 square miles
Step-by-step explanation:
Begin by counting the number of squares that the lake completely or almost completely covers. There are six of these, as indicated by an X. Then find the squares which are about half covered by the lake. These are indicated by a Y. There are three of these. The remainder of the squares that contain some portion of the lake are less than half covered, so we will not count them.
Irregular Object
1 square = 1 sq. mile
Each X counts as one square mile, and each Y counts as 0.5 (12) of a square mile.
(6 × 1) + (3 × 0.5) = 6 + 1.5 = 7.5
The area of the lake is about 7.5 square miles.
10% of 40 is 4.
1% of 40 = 40/100 = 0.4.
10% of 40 = 10.
Write 10% as a decimal number = 10% = 10/100 = 0.1
Multiply 0.1 by 40 = 0.1 × .40 = 4
