Let’s solve each problem one by one, step by step.

Problem 1:
Maddison wants carpet for her lounge. The area is 52 m², and carpet costs $6 per square meter.
→ To find total cost: multiply area by cost per square meter.
→ 52 × 6 = ?
Let’s calculate:
50 × 6 = 300
2 × 6 = 12
300 + 12 = 312
So, total cost = $312

Problem 2:
Alex needs 76 tiles. Each tile costs $20.
→ Total cost = number of tiles × cost per tile
→ 76 × 20 = ?
We can think of it as:
76 × 2 = 152, then add a zero → 1520
So, total cost = $1,520

Problem 3:
Sarah’s kitchen is 9m by 15m. We need to find the area.
→ Area of rectangle = length × width
→ 9 × 15 = ?
Break it down:
9 × 10 = 90
9 × 5 = 45
90 + 45 = 135
So, area = 135 m²

Problem 4:
Paul sees a car for $2000. It’s 10% off.
→ First, find 10% of $2000:
10% means 10/100 = 0.10
0.10 × 2000 = 200
→ Subtract discount from original price:
2000 - 200 = 1800
So, Paul pays $1,800

Final Answer:
1. $312
2. $1,520
3. 135 m²
4. $1,800
