Problem 1:

Keith bakes 12 pies a day for 5 days and then 11 more pies a day for the next 7 days. How many pies does he bake in total?

#### Step-by-Step Solution:
1. Calculate the number of pies baked in the first 5 days:
\[
12 \text{ pies/day} \times 5 \text{ days} = 60 \text{ pies}
\]

2. Calculate the number of pies baked in the next 7 days:
\[
11 \text{ pies/day} \times 7 \text{ days} = 77 \text{ pies}
\]

3. Add the pies baked in both periods to find the total:
\[
60 \text{ pies} + 77 \text{ pies} = 137 \text{ pies}
\]

#### Final Answer:
\[
\boxed{137}
\]

Problem 2:

Johnny's fence is 48m long. It's too long. He wants to divide it into 4 even parts and sell the fencing wood. How many meters does each part have to be?

#### Step-by-Step Solution:
1. Divide the total length of the fence by the number of parts:
\[
48 \text{ m} \div 4 = 12 \text{ m}
\]

#### Final Answer:
\[
\boxed{12}
\]

Problem 3:

Terry’s new house is a 4 storey house. It’s massive! If each section of the house is 3.5m high, how high is the house in total?

#### Step-by-Step Solution:
1. Multiply the height of each storey by the number of storeys:
\[
3.5 \text{ m/storey} \times 4 \text{ storeys} = 14 \text{ m}
\]

#### Final Answer:
\[
\boxed{14}
\]

Problem 4:

Amber drives to work every day. She drives 9km to work and 9km home. How many km does she drive after 7 weeks if she works Monday to Friday and doesn’t drive on the weekends?

#### Step-by-Step Solution:
1. Calculate the distance Amber drives in one round trip (to work and back):
\[
9 \text{ km} + 9 \text{ km} = 18 \text{ km}
\]

2. Calculate the number of workdays in one week:
\[
5 \text{ days/week}
\]

3. Calculate the total distance Amber drives in one week:
\[
18 \text{ km/day} \times 5 \text{ days} = 90 \text{ km/week}
\]

4. Calculate the total distance Amber drives in 7 weeks:
\[
90 \text{ km/week} \times 7 \text{ weeks} = 630 \text{ km}
\]

#### Final Answer:
\[
\boxed{630}
\]
