Question

What is the total length, in feet, of the actual walkway?

Answer 1

i think its 72 ft

:)

Answer 2

we know the trapezoids are similar, so that means all sides are at a ratio, thus

`\bf \cfrac{model}{actual}\qquad \cfrac{AB}{EF}\implies \cfrac{6}{72}\implies \cfrac{1}{12}`

that means from the model to actual, the scale is 1:12, so the large side is 12 times as large.

so for the large trapezoid

EF = 6 * 12 =... 72

EH = 4 * 12 =.. 48

HG = 3 * 12 = ..36

GF = 3 * 12 =...36

72+48+36+36 = 192.
