A farmer wants to create a rectangular fence for his goats that is 12 yd. by 15 yd. Inside the same area, the farmer will also build a small rectangular fenced garden that is 3 yd. by 6 yd. If the goats are not allowed in the garden, how many square yards is the fenced area that the goats will be allowed to roam in?(1 point)

To find the area that the goats can roam in, we need to calculate the area of the larger fenced area and then subtract the area of the smaller garden.

  1. Area of the larger fenced area (goats):
    \[ \text{Area} = \text{length} \times \text{width} = 12 , \text{yd} \times 15 , \text{yd} = 180 , \text{yd}^2 \]

  2. Area of the smaller garden:
    \[ \text{Area} = \text{length} \times \text{width} = 3 , \text{yd} \times 6 , \text{yd} = 18 , \text{yd}^2 \]

  3. Area for the goats:
    \[ \text{Area for goats} = \text{Area of the larger area} - \text{Area of the garden} = 180 , \text{yd}^2 - 18 , \text{yd}^2 = 162 , \text{yd}^2 \]

The fenced area that the goats will be allowed to roam in is 162 yd².

Thus, the correct response is: 162 yd².
