Answer:
9. Area of triangle=
10. Base= 16 ft and Height= 15 ft.
11. 120 ft²
Step-by-step explanation:
Given: Base of triangle= 16 ft
Length of leg of triangle= 17 ft.
As shown in the picture that median has bisected the triangle and forming two right angle triangle.
∴ Each base of right angle triangle=
Now, finding the height of triangle by using pythagorean theorem.
We know, , where h is hypotenous, a is height or opposite and b is base or adjacent of triangle.
⇒
⇒
Subtracting both side by 64
⇒
taking square root on both side, remember; √a²=a
⇒a=
Hence, height of triangle is 15 ft.
Next, finding the area of triangle.
Formula; Area of triangle=
⇒ Area of triangle=
∴ Area of triangle= 120 ft²
Answer:
Volume of the prism is 648
Step-by-step explanation:
Given:
Base of the prism is rectangular in shape
Height of the prism = 6 cm
Base length of the prism= 12 cm
Base width of the prism= 9 cm
To Find:
Volume of the prism=?
Solution:
Volume of the prism ,
V= Base area of the prism x Height of the prism
Here in the figure base of the prism is in Rectangular form
So the base area of the prism = area of the rectangle
We know that the area of the rectangle is = length x height
Substituting the values
Area of the Rectangle = 12 x 9
Area of the Rectangle = 108
So the are of the base of the prism is 108
Now
Volume of the prism,
V= 108 X 6
V= 648
