Answer:
12
Step-by-step explanation:
The area of a rectangle is l × w.
x × 11/3 = 44
x = 44 × 3/11
x = 12
If the volume and the height are known, then we can find the base area of a rectangle prism by these steps:
Find the area of two sides (Length*Height)*2 sides
Find the area of adjacent sides (Width*Height)*2 sides
Find the area of ends (Length*Width)*2 ends
Add the three areas together to find the surface area
We know that,
Surface Area of Rectangular Prisms :
A rectangular prism has 2 ends and 4 sides. Opposite sides have the same area. The surface area is the sum of the areas of all six sides.
Here, we have,
to find the surface area of Rectangular Prisms:
Find the area of two sides (Length*Height)*2 sides
Find the area of adjacent sides (Width*Height)*2 sides
Find the area of ends (Length*Width)*2 ends
Add the three areas together to find the surface area
Example:
The surface area of a rectangular prism 5 cm long, 3 cm. wide and 2 cm. high = 5*2*2 + 3*2*2 + 5*3*2 = 20 + 12 + 30 = 62 cm^2.

each class has 20 students
3 classes // 20 x3= 60
60 students + 11 teachers+13 parents = 84 people total
as you cant put half people in boats you round up to 90
meaning you would need 9 boats to have enough space for all of them xx
hope this helped x
