Answer 1

380 feet 65x2=130 45x2=90 35x2=70 45x2=90 Total=380

Answer 2

You will need 380 feet of fencing

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
