Given:
The sides of a right triangle are 2 cm, 3 cm, and 3.6 cm.
To find:
The area of the right triangle.
Solution:
Area of a triangle is:
In the given triangle 3.6 cm is the largest side, it means 3.6 cm is the length of the hypotenuse. So, 2 cm and 3 cm and the base and height of the triangle.
Now, the area of the given triangle is:
Therefore, the area of the given triangle is 3 square cm.
Answer:
The surface area of the box in terms of l is
Step-by-step explanation:
The length of the box =
The height of the box =
The volume of the box can be obtained by multiplying the surface area of the base by the height of the box.
The surface area of the base of the box is a square, so it will be obtained by multiplying
hence volume =
Notice that we are told to give our answer in terms of l, so we will make h the Subject of the formula in the above equation.
In the next phase, we are to find the surface area of the box.
The box has a square base, hence it will be made up of
2 squares with 4 rectangles. This is assuming the top is closed.
This means the surface area will be
recall
Hence, surface area =
The surface area of the box in terms of l is
