Answer:
1386cm squared
Step-by-step explanation: first find the diameter.
132=pi x diameter
132=22/7xd
multiply both sides by 22/7 and you'll get 42cm
then find the area by doing this.
22/7x21x21 which gives you 1386cm squared.
the 21 is the radius.
Answer:
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
