The similar figures, parallelograms ▱QUAD and ▱STOP, have a ratio of 3:1 between their corresponding sides. If ▱QUAD has a perimeter of 210 centimeters, then ▱STOP has a perimeter of

a0 centimeters.

The similar figures, parallelograms ▱QUAD and ▱STOP, have a ratio of 3:1 between their corresponding sides. If = 10, then =
a0.
The similar figures, parallelograms ▱QUAD and ▱STOP, have a ratio of 3:1 between their corresponding sides. If ▱STOP has an area of 64 square yards, then ▱QUAD has an area of
a0 square yards.

Answer 1

perimeter scales as the given ratio. P(QUAD) = 3*P(STOP)
area scales as the ratio squared. A(QUAD) = 9*A(STOP)
