Is this a right triangle or not? If it's a right triangle, you could use the Pythagorean Theorem to find the length of the 3rd side, which would be the hypotenuse. Thus, 14^2 + 4^2 = c^2, where c is the length of the hypot.

Then 196 + 16 = 212, and this is c^2. Then c, the length of the hypotenuse, is sqrt 212, or approx. 14.6 inches.

This does not agree with any of the four possible answers. Thus, you must look at each of these possible answers and eliminate any that could not be correct.

for example: if you take 10 inches and add 4 inches, you get 14 inches. The result would not be a triangle, but rather a straight line.

Check out the others similarly.

Find the area of the figure?

Alex777 [14]

Answer:

14 m

Step-by-step explanation:

For the triangle, you use the formula A=1/2bh. So in this case it's 3×4×1/2. 3×4 is 12, times 1/2 is 6 m. Now for the rectangle it's just 2×4 which is 8. 8+6 is 14. Hope this helps! If you are still confused please comment!

A company is building a new park in the shape of a circle with a 25 ft diameter. Portions of the new park will be covered with g

emmasim [6.3K]

Answer: The area of the regions covered by grass is approximately 313.375 sq ft.

Step-by-step explanation:

Given: A company is building a new park in the shape of a circle with a 25 ft diameter.

Then radius = $\dfrac{25}{2}=12.5\ ft$

Required area = Area of circle - Area of rectangle + Area of triangle

Formula: Area of circle = $\pi r^2$

Area of rectangle = length x width

Area of triangle = 0.5 x base x height

Area of circle = $(3.14)(12.5)^2=490.625\ \text{ft}^2$

Area of rectangle = 20 ft x 10ft = 200 ft²

Area of triangle = 0.5 x 7 x 6.5 = 22.75 ft²

Required area = 490.625 -200+22.75 = 313.375 ft²

Hence, The area of the regions covered by grass is approximately 313.375 sq ft.
