Answer: A.90 cm^2
Step-by-step explanation: A= a+b/2 h
A= 17.5+12.5/2 *6
A = 30/2*6
A= 15*6
A=90
If you would like to know how many centimeters should you cut off, you can calculate this using the following steps:
1 1/2 meters = 3/2 meters = 1.5 meters = 150 centimeters
250 centimeters - 1 1/2 meters = 250 centimeters - 150 centimeters = 100 centimeters = 1 meter
The correct result would be 100 centimeters.
The radius of a circle is
always half of the diameter of the circle. In this case, the diameter is

, meaning that when we halve

, we will get our radius. Therefore, the radius of the circle is

. Hope this has helped you understand and have a great day!
