This is wrong to me. Sorry

A sentence (sometimes also called a formula) is simply a string of characters or symbols.

E.g., “sin2 x + cos2 x = 1” is a sentence as is “5 + 4”.

A statement is a sentence that is definitely either true or false.

What are the Euclidean postulates?

A straight line segment may be drawn from any given point to any other. A straight line may be extended to any finite length. A circle may be described with any given point as its center and any distance as its radius. All right angles are congruent.

What are the 5 postulates described by Euclid?

Euclid's postulates were: Postulate 1: A straight line may be drawn from any one point to any other point. Postulate 2:A terminated line can be produced indefinitely. Postulate 3: A circle can be drawn with any center and radius. Postulate 4: All right angles are equal to one another.

What is perimeter for the semi-circle/rectangle image and area for the other one

Answers

I don’t know the answer but first you need to find the perimeter for each shape that is divided by the lines. I also provide a picture above with formulas to figure out the perimeter

Answer:

A= 551.625

Explanation:

Ignore the semi-circles.
Take the high and width of the remaining rectangle(15 and 25)
Multiply them together =375
Rectangle =375

Take the semi-circles and make them a circle. The diameter is the same as the height, so 15
15/2 =7.5, the radius

Square the radius(=56.25) and multiply it by pi to get 176.625

Add the area of the circle and the rectangle to get the answer.
