Does someone know the area of this trapezoid and round it to the nearest tenth

Step-by-step explanation:

The formula for determining the area of a trapezium is expressed as

Area = 1/2(a + b)h

Where

a and b are the lengths of the opposite side of the trapezium

h is the height of the trapezium.

From the diagram

a = 1.1 m

b = 2.4 m

To determine the height, h, we would apply the sine trigonometric ratio which is expressed as

Sine θ = opposite side/hypotenuse

Therefore,

Sin 45 = h/1.8

h = 1.8sin45 = 1.8 × 0.7071 = 1.273

Therefore

Area of trapezoid

= 1/2(1.1 + 2.4)1.273

= 2.2m²

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
