Answer:
Step-by-step explanation:
1.
Formula for Area of a parallelogram: A = bh
So multiply the base (25cm) by the height (16cm) to get 400cm^2.
2.
Volume formula l x w x h
Multiply the length of the pool (20ft) by the width (15ft) by the height (6ft) to get 1,800ft^2
3.
Formula for Area of a trapezoid A= a+b/2 * h
Where a is (12.6in), b is (15in), and h is (3.4in) just plug in the numbers into the formula to get 46.92in^2
4.
Same thing as number one, use the Area of a parallelogram formula A = bh
