Answer:

Option D, 336

Step-by-step explanation:

The first step is to find the area of the flowerbed. 25*9=225 feet squared. The next step is to pretend that the sidewalk takes up the full space, and then subtract the area of the flower garden within to find the area of the sidewalk. Since the sidewalk is 4 feet wide, it makes the dimensions of the sidewalk added to the garden 8 feet wider on all sides. This means that the total area of the two is (25+8)*(9+8)=33*17=561 squared feet. Now, all you need to do is to subtract the area of the flower garden. 561-225=336 feet squared, or option D. Hope this helps!

Answer:

(20x30)= 600

that's the area of rectangular plot

3ft wide sidewalk means both +3 on left and +3 on right, also both +3 up and +3 down

which means u have to do 26x36=936

then subtract

936-600=336 square feet

Congruence Properties

In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!

The Reflexive Property of Congruence

The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.

Note that all of these choices but the last have 1-number responses. The last choice involves collecting data: the ages of the concert attendees. So only the last pertains to statistics.
