Area of a square = Side x Side (length x width)
A = 1.69 m²
Length = √area of square
L = √1.69 m²
L = 1.3 m
Check Work: 1.3² = 1.3 m x 1.3m
= 1.69 m²
To solve this problem we can find the area of the whole rectangle, then find the area of the smaller white rectangle inside the whole rectangle. Lastly, we can subtract the area of the smaller rectangle from the area of the whole rectangle which leaves us with the area of the shaded region.
Area of whole rectangle = length x width
= (3x + 6) (2x + 4)
= 6x squared + 24x + 24
Area of small rectangle = length x width
= (x-3) (x - 1)
= x squared - 4x + 3
Area of shaded region = area of whole rectangle - area of small rectangle
= 6x squared + 24x + 24 - x squared + 4x - 3
= 5x squared + 28x + 21

=
which is not equivalent to the given trigonometric ratio, thus(B) is incorrect.
(C) The given trigonometric ratio is :
=
which is not equivalent to the given trigonometric ratio, thus(C) is incorrect.
(D) The given trigonometric ratio is :
=
=
=
=
which is not equivalent to the given trigonometric ratio, thus(D) is incorrect.
The answer is: -1/5 or -0.2
One side of the original triangle is 15 units long and the side of the equivalent side of the dilated triangle is 3 units long. Therefore the magnitude of the enlargement scale factor is 3/15 or 1/5;
The answer is -1/5 as the transformation resulted in an inversion as well as an enlargement/dilation, therefore the answer is negative.
