Arectangle has a a perimeter of 72 ft. the length and width are scaled by a factor 3.5.

what is the perimeter of the resulting rectangle?

The perimeter of the resulting rectangle is

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z-----> the scale factor

x------> the perimeter of the dilated rectangle

y-----> the perimeter of the original rectangle

so

In this problem we have

substitute and solve for x

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
