Quadrilateral ABCD in the figure below represents a scaled-down model of a walkway around a historic site. Quadrilateral EFGH re

Mkey [24]

the picture in the attached figure

Step 1

Find the perimeter of the scaled-down model of a walkway (Quadrilateral ABCD)

$P=AD+DC+CB+BA\\P=3+2+2+4\\ P=11 in$

Step 2

Find the scale factor

if Quadrilateral ABCD is similar to Quadrilateral EFGH

then

$PerimeterEFGH=PerimeterABCD*scale factor$

$scale.factor=\frac{EF}{AB} \\ \\ scale.factor=\frac{60}{4} \\ \\ scale.factor=15\frac{ft}{in}$

Step 3

Find the perimeter of the actual walkway (Quadrilateral EFGH)

$PerimeterEFGH=PerimeterABCD*scale factor$

$PerimeterEFGH=11*15$

$PerimeterEFGH=165 ft$

therefore

the answer is

$165 ft$

MariettaO [177]

20+8q -88= -12
8q -68 = -12
8q = 68-12
8q = 56
q= 56/8
q= 7
