ngle. find the area of the rectangle when the width is 10 centimeters.
1 answer:
Answer:

When w=10 then A=220 square cm
Step-by-step explanation:
To calculate an area of a rectangle, use the formula A=l*w. We know the length is 8cm less than 3 times the width. So l = 3w - 8.
So the area is 
If the width is 10 then substitute w=10 into the polynmial.
