<em><u>Answer</u></em>
In order to use the distributive property I first get the amount of the water fell in ;
<u>One </u><u>year</u>
1.68mm
<u>A </u><u>half</u><u> </u><u>a </u><u>year</u>
½× 1.68mm
= 0.84mm
<u>One </u><u>and </u><u>a </u><u>half </u><u>years (</u><u>Using </u><u>the</u><u> </u><u>distributive</u><u> </u><u>property</u><u>)</u>
1.68mm + 0.84mm
<u>1</u><u>6</u><u>8</u><u>m</u><u>m</u> + <u>8</u><u>4</u><u>m</u><u>m</u>
100. 100
(168÷100) + (84÷100)
(168+84) ÷ 100
252 ÷ 100
<u>2</u><u>5</u><u>2</u>
100
= 2.52mm
Therefore the variation in the water level in the time period was 2.25mm
