Sara is making a model tent. How much material will she need? Explain the process to solve and show all calculations

her tents measurements are
base= 4cm
length=15cm
and two of the sides are both 5cm

1 answer

To determine how much material Sara will need to make the tent, we need to calculate the surface area of all the sides of the tent.

First, we calculate the area of the base:
Area of base = base x length
Area of base = 4cm x 15cm
Area of base = 60 cm²

Next, we calculate the area of the sides:
Area of side 1 = base x height
Area of side 1 = 4cm x 5cm
Area of side 1 = 20 cm²

Since there are two sides with the same measurements, we calculate the total area of the sides by multiplying the area of one side by 2:
Total area of sides = 20 cm² x 2
Total area of sides = 40 cm²

Now, we add the area of the base and the total area of the sides together to find the total material needed:
Total material needed = Area of base + Total area of sides
Total material needed = 60 cm² + 40 cm²
Total material needed = 100 cm²

Therefore, Sara will need 100 cm² of material to make her tent.
