Area of a trapezium = (h/2)[a + b]
h = 14
a = 10
We need to find b!
B = 10 + 4 + 4 = 18
So,(14/2)[10 + 18]
          7    *    28       =  196 square inches.

Hope this helps :)
We can easily find the area of the square so lets solve that first.
10x14= 140

Now we need to solve the triangles outside the square
14x4=56
This would the area of a rectangle/square and thats a triangle so cut it in half
56/2=28

Square (140) + 2 Triangles (28 + 28) = 196

Find the gradient of the line segment between the points (-8,6) and (-10,14)

Answers

The required gradient of the line between the points (-8,6) and (-10,14) is -4.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The gradient of the line segment between points (-8,6) and (-10,14) is given as,

The gradient of the line = slope of the line,
m = (y₂ - y₁) /  (x₂ - x₁)

Substitute the value in the above equation,
m = 14- 6 / -10 + 8
m = 8 / -2
m = -4

Thus, the required gradient of the line between the points (-8,6) and (-10,14) is -4.
