your neighbors needs to put a fence around her front yard and a separate fence around her back yard her front yard is 65 feet long and 45 feet wide her back yard is 35 feet long by 45 feet wide how much fencing should she buy the fence is not attracted to the house
Answer:
You will need 380 feet of fencing
Step-by-step explanation:
The perimeter of a rectangle is :
P=2L+2W
L: Length of the rectangle
W: Width of the rectangle
For the front yard:
\(Pf=2*65+2*45\\\\Pf=130+90\\\\Pf=220\)
The front yard has a perimeter of 220 feet
For the back yard
\(Pb=2*35+2*45\\\\Pb=70+90\\\\Pb=160\)
The back yard has a perimeter of 160 feet
The necessary fencing is the sum of the two perimeters, so you will need 220+160 = 380 feet
