Answer:
42.875
Step-by-step explanation:
First you find the x-intercepts and the vertex of the equation.
(-5, 0), (-2, 0), (-3/2, 49/4)
You use those coordinates to find the sides of the triangle and then you use the lengths to find the semiperimeter.
Lastly, you use Heron's formula to compute the area.
Answer:
80
Step-by-step explanation:
area of trapezoid is given by formula
Area = 
h
where a is one base, b is another base and h is height
In given case, we have
a= 7+7+3 = 17
b= 3
h= 8
Substituting the values
Area= 
x 8
= 
x 8
= 10 x 8
= 80
!
Answer:
The length of A will be 8 as
The ratio between the sides are 4:1
Since Side is 2 therefore side A=2*4
=8
Hope u got your answer..
