<h2>Answer:</h2>
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>
Answer:
where R is the R-value and t is the thickness in inches.
Step-by-step explanation:
We are given the following in the question:
The R-value of fiberglass insulation and f its thickness have a linear relation.
Let R be the R-value and t be the thickness. Then, the equation can be written as:
where a and b are constants.
When t = 3.5, R = 11
When t = 6, R = 19
Solving the two equation, using the elimination method, we have,
Thus, the linear relationship is given by:
where R is the R-value and t is the thickness in inches.
