Find the Area of the figure below, composed of a rectangle and a semicircle. Round to the nearest tenths place.
1 answer:
Answer:
Area of the composite figure = 175.1 square units
Step-by-step explanation:
Area of the composite figure given in the picture = Area of the parallelogram + Area of the semicircle formed on one side of the parallelogram
Area of the parallelogram = Base × Height
= 30 × 5
= 150 square units
Area of the semicircle =
=
= 8π
= 25.13
≈ 25.1 square units
Now area of the complete figure = 150 + 25.1
= 175.1 square units

Answer:
- Exact distance =
feet
- Approximate distance = 127.2792 feet.
===========================================================
Explanation:
The area of the square is 8100 square feet, abbreviated ft^2.
Apply the square root to find the distance from any base to its adjacent counterpart (eg: from 1st to 2nd base). So we get sqrt(8100) = 90 ft as that side distance. Notice that 90*90 = 8100.
If you were to draw a line from 1st base to 3rd base, then you would split the square into two congruent right triangles. Each right triangle is isosceles (the two legs being 90 ft each).
Use the pythagorean theorem to find the hypotenuse.
The distance from 1st to 3rd base is roughly 127.2792 feet.
