Answer:
20 cm
Step-by-step explanation:
Assuming that the side lengths you've written are the only side lengths of the shape, meaning it would be a trapezoid, all you do is add them up together.
3 + 5 + 5 + 7 = 20
The simplification form of the expression is 3x²/2 + 2x or three-halves x squared + 2 x option second is correct.
<h3>What is the area of the rectangle?</h3>
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
We have:
A community garden with raised beds is being redesigned. The area of the new rectangular beds can be expressed as one-half x (3 x + 4).
The expression:

By using the distributive property:


Thus, the simplification form of the expression is 3x²/2 + 2x or three-halves x squared + 2 x option second is correct.

Answer:
Step-by-step explanation:
<u>The diameter is the hypotenuse of the triangle:</u>
- d = √8²+6² = √100 = 10 cm
<u>Area of the semicircle:</u>
- A = 1/2πr² = 1/2(3.14)(10/2)² = 39.25 cm²
<u>Area of the triangle:</u>
- A = 1/2bh = 1/2(6)(8) = 24 cm²
<u>Shaded area:</u>
