Answer:
400m of fencing is required to surround the area.
Step-by-step explanation:
First we need to find one side of the square. We know the area of a square is:
A = x²
We can use this information to find the length of a side of the square.
10000m² = x²
x = √10000m²
x = 100m
Now that we know what the length of the square yard is, we can calculate the perimeter. The perimeter of a square is:
P = 4x
For our problem:
P = 4(100m)
P = 400m
400m of fencing is required to surround the area.
Answer:
Step-by-step explanation:
Please consider the diagram.
We have been given that the volume of the triangular prism is 54 cubic units. We are asked to find the value of x.
We know that volume of triangular prism is equal to area of base times height of the prism.
We can see from the attachment that base of prism is triangle. The area of the base of prism would be equal to area of triangle.
Now we will multiply base area with height of prism .
Let us equate volume of prism with 54 as:
Take positive square root on both sides:
Therefore, the value of x is 3 and option A is the correct choice.
Answer:
∠ BCD = 122°
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral sum to 180° , then
∠ BCD = 180° - 58° = 122°
