Answer:
38 yards²
Step-by-step explanation:
Area of trapeziods= ½(a+b)×height
a and b are the parallel lengths of the trapezoid.
Area of trapeziod= ½ (5.6+13.4)×4= 38 yards²
Therefore, the correct option is B

Answer:
For this case is the rectangle is dilated a factor of 2.2 we assume that the expansion is in all the dimensions so then the new length and width are:
Step-by-step explanation:
The area of a rectangle is given by
For this case is the rectangle is dilated a factor of 2.2 we assume that the expansion is in all the dimensions so then the new length and width are:
And the area would be (2.2)^2 times the initial area since is defined as
