A triangle has a base of 9 feet and a height of 12 ft. What is the area of a triangle? A. 42ft^2 B. 54 ft^2 C. 84 ft^2 D. 108 ft^2​
A triangle has a base of 9 feet and a - 1

Answers

Answer 1
Answer:

Answer:

The correct answer is option B. 54 ft^2

Step-by-step explanation:

Formula:-

Area of triangle

Area A = bh/2

b - Base of triangle

h - Height of triangle

To find the area of triangle

Here base b = 9 ft and height h = 12 ft

Area, A = bh/2 = (9 * 12)/2 = 54 ft^2

Therefore the area of given triangle is 54 ft^2

The correct answer is option B. 54 ft^2
Answer 2
Answer:

Answer:54sqft

Step-by-step explanation:

A=b*h/2

A=9*12/2=54sqft

Calculate the perimeter and area of the following square if a= 19

Answers

we are given

Area:

side=a=19

we know that

area of square = side*side

Area=a*a

now, we can plug value

and we get

Area=19*19

Area=361

Perimeter:

perimeter=4a

perimeter=4*19

perimeter=76

Formula for perimeter of a square: P = 4a

Formula for area of a square: A = a²

a is given as:

19

Plug this value for a into the above formulas to solve for perimeter and area.

P = 4a

P = 4(19)

P = 76

-----------------------------------------------------------------------------------------------------------------

A = a²

A = 19²

A = 361

Answer:

P = 76 units; A = 361 units².

You take 75% and turn it into a decimal (0.75). Then you multiply 0.75 by 124 = 93

In geometry words describe a way to seperate triangles Into other triangles

Answers

start at one of the vertices and draw a line from there to a point on the oposite side, not ending at another vertex
There are many ways of dividing a triangle, two ways are mentioned below.

Method 1: Dividing a triangle into triangle of three equal areas

After trisecting one side of the triangle connect the two points that trisect the side to the opposite vertex which will make all three triangles have the same length of base and height.

Method 2: Dividing a triangle into two

This method is pretty simple if you are just going straight down the middle to make the two triangles of even base and height.

I hope this helps. If any false information was given I apologize in advance.
