Check the picture below.

\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=\stackrel{bases}{parallel~sides}\\ h=height \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{left-side trapezoid}}{ \begin{cases} a=2\\ b=5\\ h=3 \end{cases}}\implies A=\cfrac{3(2+5)}{2}\implies A=\cfrac{21}{2}\implies A=10\frac{1}{2} \\\\\\ \stackrel{\textit{right-side trapezoid}}{ \begin{cases} a=1\\ b=4\\ h=3 \end{cases}}\implies A=\cfrac{3(1+4)}{2}\implies A=\cfrac{15}{2}\implies A=7\frac{1}{2}

Find the area of a rhombus, whose diagonals are 10cm and 5.2cm<br>step by step ​
Free_Kalibri [48]
The area of a rhombus is p x q divided by 2.

p and q are both the diagonals of the shape.

In this case, we would do 10 x 5.2 divided by 2, which gives us 26, so your answer is 26 cm^2 (squared).

Hope this helps!

Quadrilateral A has side lengths 6, 9, 9, and 12. Quadrilateral B is a scaled copy of Quadrilateral A, with its shortest side of
Varvara68 [4.7K]

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

a) The scale factor from Quadrilateral A to Quadrilateral B = smallest side length of side B / smallest side length of side A = 2 / 6 = 1/3

Scale factor = 1/4= 1 / 3

The side length of 6 in A corresponds to a side length of 2 in B

Side length of B that corresponds with side length of 9 in A = scale factor * 9 =  1/3 * 9 = 3

The side length of 9 in A corresponds to a side length of 3 in B

Side length of B that corresponds with side length of 12 in A = scale factor * 9 =  1/3 * 12 = 4

The side length of 12 in A corresponds to a side length of 4 in B.

c)  perimeter of Quadrilateral B = sum of side lengths of quadrilateral B = 2 + 3 + 3 + 4 = 12 units
