Answer:
x = 12, y = 16
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
18(2x + 6) = 540 ( divide both sides by 18 )
2x + 6 = 30 ( subtract 6 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
-------------------------------------------
and
=
, substitute values
=
( cross- multiply )
27y = 432 ( divide both sides by 27 )
y = 16
Plug the coordinates into the distance formula and solve.
5*36.95= $<span>184.75
2*42.99= $</span><span>85.98
3*38.95= $</span>116.85
1*52*0.6=$<span>31.20 (40% off) multiply by 0.6)
Add 184.75+85.98+116.85+31.20=$</span>418.78 - 20% thus: 418.78*.8= $ <span>335.024</span>
Area ≈ 12.57
Circumference ≈ 12.57
