Instructions: select the correct answer from each drop-down menu. the sides of ∆abc are 30 units, 40 units, and 60 units long. the corresponding sides of ∆xyz are r times as long as the sides of ∆abc. the expression that gives the perimeter of ∆xyz is . if the area of ∆abc is n square units, the area of ∆xyz is square units

The sides of ∆ABC are 30 units, 40 units, and 60 units long.

The perimeter will be = units

Given is that ∆ABC and ∆XYZ are similar and the corresponding sides of ∆XYZ are 'r' times as long as the sides of ∆ABC.

So, perimeter of ∆XYZ will be : units.

----------------------------------------------------------------------------------------

The area of ∆ABC is n square units, so area of ∆XYZ will be :

=

= square units.

this is answer of 144 cubic meters
