Area of the triangle = (1/2)*base*height
For right triangle base and height can be legs.
We have one leg = 5 ft. (Lets think it is a base.)
We need to find the other leg.
We are going to use Pythagorean theorem.
5² + b²=13²
b²=144
b=12 (It is going to be our height.)
Area of the triangle = (1/2)*5*12= 30 ft²
Area of the triangle = 30 ft²
Answer:
I believe it is 1728 cubic centimeters, however I might be wrong
Hope it helps : )

Answer:
Circumference is 18.84 feet. Area is 28.26 square feet.
Step-by-step explanation:
Given:
Radius of the circle, 
The value of
is 3.14.
Now, circumference of a circle of radius
is given as:

Also, area of the circle of radius
is given as:

Therefore, the circumference of the circle is 18.84 feet and area of the circle is 28.26 square feet.
Answer:
Area = 36 sq units
Step-by-step explanation:
An isosceles trapezoid have two triangles and probably a rectangle or a square.
To find the area, let's determine the height of the trapezoid.
The base length of one of the triangle
= (15-9))2
= 6/2 = 3
The height will be x
X /sin 45= 3 / sin 45
X= 3
The area of the trapezoid
= 1/2(a+b)h
Where a = 15
b = 9
h = 3
Area= 1/2(15+9)3
Area= 1/2 *24*3
Area= 12*3
Area = 36 sq units
