Answer:
6.333
Step-by-step explanation:
Our triangle vertices are
(1,1)(5,1)(2,9)
We are to perform interpolation at point(3,5)
x and y values are interpolated
On vertices (5,1)(2,9)
x = 3
x1 = 5
X2 = 2
Y1 = 1
Y2 = 9
Formula for interpolation
Y = [y1+(x-x1)(y2-y1)]/x2-x
Y = 1+(3-5)(9-1)/2-5
Y = 1+[-2*8/-3]
Y = 1+16/3
From here we use use LCM to get:
19/3 = 6.333

42 square units
<h2>Step-by-step explanation:</h2>For a better understanding, I add an EFGH Rectangle.
The area of EFGH Rectangle = p x l
The area of EFGH Rectangle = 10 x 8
The area of EFGH Rectangle = 80cm²
The area of BHA Triangle = 1/2 x a x t
The area of BHA Triangle = 1/2 x a x t
The area of BHA Triangle = 1/2 x 6 x 4
The area of BHA Triangle = 2 x 6
The area of BHA Triangle = 12cm²
The area of AGD Triangle = 1/2 x a x t
The area of AGD Triangle = 1/2 x 4 x 2
The area of AGD Triangle = 4cm²
The area of CFD Triangle = 1/2 x a x t
The area of CFD Triangle = 1/2 x 2 x 6
The area of CFD Triangle = 6cm²
The area of BEC Triangle = 1/2 x a x t
The area of BEC Triangle = 1/2 x 8 x 4
The area of BEC Triangle = 4 x 4
The area of BEC Triangle = 16cm²
The area of the trapezoid = EFGH Rectangle - (BHA Triangle + AGD Triangle + CFD Triangle + BEC Triangle)
The area of the trapezoid = 80 - (12 + 4 + 6 + 16)
The area of the trapezoid = 80 - 38
The area of the trapezoid = 42cm²
<h3>Conclusion :</h3>The area of the trapezoid is <u>42 square units</u>
