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

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
