Answer:
B) -15
Step-by-step explanation:
50 yards for 1 lap
50 yards x 18 laps = 900 total yards
now divide the amount he swam by the total amount he wants to swim:
738 / 900 = 0.82 = 82%
Answer is B
To solve this we will divide the given composite figure into three figures. The three figures will be 2 squares and 1 rectangle. Let's find their areas and add them!



<em>Thus, The area of 1st square is 9m²...</em>
- The area of second square will be also 9m², because the sides of both squares are equal.
<h3>
Now area of the reactangle⤵️</h3>
- Length = 6m
- Breadth = 7+3=10m



<em>Thus, The area of rectangle is 30m²....</em>
- Now, Add area of all the figures to get the total area.

<h3><em>Therefore, The total area of the composite figure is 48m²...~</em></h3>
