Question

Quadrilateral CDEF is dilated by a scale factor of 3/4 form quadrilateral C'D'E'F'. What is the measure of side FC? F' 21 Ε' 21 21 C' D' 21

Answer 1

We will find the measurement of side FC as follows:

$21=x\cdot\frac{3}{4}$

Now, we solve for x:

$\Rightarrow x=\frac{21\cdot4}{3}\Rightarrow x=28$

From this, we have that the measure of side FC is 28 units.
