A = 2w² + 40w
If the w = width and the length is 40 more than twice the width, we can write the dimensions of the soccer field as follows:
w for the width and (2w + 40) for the lenth. We multiply these two together to find the equation above for area
If the width is w then the length = 2w + 40, so the area
= w(2w + 40)
= 2w^2 + 40 w
Answer:
Step-by-step explanation:
Given
-- folded twice
Required
The area of the new rectangle
When the length was folder, the new length is:
When the width was folder, the new width is:
So, the new area is:
#1
#2
