The expression $15x+11$ represents the perimeter of the trapezoid. What is the length of the fourth side? A trapezoid. The shorter base is labeled 3 x plus 4. The legs are labeled 2 x plus 3 and 4 x minus 1. The length is .

Step-by-step explanation:

Given that:

Perimeter of the trapezoid =

Shorter base =

One leg =

Second base =

To find:

The length of fourth Side = ?

Solution:

Let us have a look at the perimeter of a trapezoid.

Perimeter = Sum of all the sides

Let the fourth side =

Using the formula and putting the given values:

Fourth side is:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

correct answer:

b.(19,-2)
