240 cm², A = 300 cm², and 540 cm²

Step-by-step explanation:

1) The area of a parallelogram is A = bh, so:

A = (20)(12)

A = 240 cm²

2) Similarly, the area of a rectangle is A = bh, so:

A = (15)(20)

A = 300 cm²

3) The composite area is the sum of both the rectangle's area and the parallelogram's area, so:

240 cm² + A = 300 cm² = 540 cm²

P=

20x12=240

R=

20x15=300

240+300

Step-by-step explanation:

32

Step-by-step explanation:

512/16=32

to get area you do LxW=A

so we just do the reverse

A/W=L
