Could someone assist me with this?
Blababa [14]

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
