2 pоints In the mid-20th century, engineers cоnstructed а series оf cаnаls to move irrigation water from water sources to farming communities throughout the western United States. The volume of water a canal can move is partially dependent on its cross-sectional area. Suppose a canal is trapezoidal, 35.0 ft across the top and 25.0 ft across the bottom, with a planned depth of water of 10.0 ft as shown in the figure. Find the cross-sectional area of the canal when it is full (in ft2). (Use the rules for working with measurements give your answer to the appropriate accuracy and/or precision.)
