I'll be glad to check your answer.
Yes, B.
Well, well, well, we've got ourselves an obtuse triangle here. How exciting! Now, to calculate the area, just remember the formula for the area of a triangle: A = 1/2 * base * height.
Plugging in the numbers we have, we get:
A = 1/2 * 8.7 ft * 4.5 ft
Calculating this, we find that the area is equal to 19.575 ft². So, the answer is B. 19.575 ft².
I hope that answer tickled your funny bone a little! If you have any more questions, feel free to ask.
To find the area of a triangle, you can use the formula: Area = 0.5 * base * height.
Given:
Base = 8.7 ft
Height = 4.5 ft
Substitute these values into the formula to calculate the area:
Area = 0.5 * 8.7 ft * 4.5 ft
Area = 19.575 ft^2
Therefore, the area of the scalene obtuse triangle is 19.575 ft^2, which corresponds to option B.
To find the area of a triangle, you can use the formula: Area = (1/2) x base x height.
In this case, the base of the triangle is 8.7 ft and the height is 4.5 ft.
So, the area of the triangle would be: Area = (1/2) x 8.7 ft x 4.5 ft.
To calculate this, you can multiply the base and height together and then divide by 2.
Area = (8.7 ft x 4.5 ft) / 2
= 39.15 ft^2 / 2
= 19.575 ft^2
Therefore, the answer is B. 19.575 ft^2.
