What is the area of a triangle?The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
From the given figure,
Height of a triangle is 8 units and the base of the triangle is 6 units.
Here, area = 1/2 ×6×8
= 24 square units
Therefore, option B is the correct answer.

PLEASE ANSWER!!!!!!
The semicircle below has a diameter of 20. Find the area of the blue region.
Answer:
61
Step-by-step explanation:
Use the area of semicircle minus the area of the triangle. Area of the semicircle is 10^2 * pi / 2 = 50 pi, the area of the triangle is 12*16/ 2 = 96. The the area for the blue part is 50 pi - 96 = 61.07963268 or 61.
If it is helpful, plz give me Brainliest.
Answer:
50pi - 96
Step-by-step explanation:
The radius of the semicircle is 10, so the area of the entire semicircle is 1.2*10^2 pi = 50pi
The white triangle has an area of 1/2*12*16 = 96 so subtracting it shows that the blue area is 50pi-96
Brainly plz help only three questions and don't answer for point kinda rude

The formula to find the surface area (S) of a rectangular prism with a length (l), a width (w) and a height (h) is:
S = 2lw + 2wh + 2lh
What is the surface area, in inches, of a rectangular prism with a length of 5, a width of 4, and a height of 6?
Answer:
148 in^3
Step-by-step explanation:
S= 2lw + 2wh + 2lh
S = (2 x 5 x 4) + (2 x 4 x 6) + (2 x 5 x 6)
S = 40 + 48 + 60
S = 148

Answer:
65°
Step-by-step explanation:
the angle of a straight line has to add up to 180°
if it doesn't, it's not a straight line
115° and x are supplementary angles
meaning we know they have to add up to 180°
so simply subtract
180- 115 =
65°
you can check work by adding
115+65= 180
Answer: 65
180-115=65
Step-by-step explanation:
A straight line is always 180 so I subtracted 115 from 180.
