In Kendall's back yard play areas he swings are 11.3 feet wide. The slide is 6 1/5feet wide. In decimal form, what is the total width of swings and slide ?

17.5 feet

Step-by-step explanation:

Width of the swing = 11.3 feet

Width of the slide =

Total width of the swing and slide = Width of the swing + Width of the slide 11.3 feet + 6.2 feet = 17.5 feet

In order to find total of two or more things, we use addition.

The addition is taking two or more numbers and adding them together.

It is one of the four basic operations of arithmetic: subtraction, multiplication and division.

Symbol + is used to denote addition.

Addition can be used to solve joining problems, separation problems, part - part - whole problems and comparison or equivalent problems.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
