Answer:

Explanation:

The original rectangle has dimensions of 70 x 35.

Therefore, we can find its perimeter and area with the standard formulas.

A = 70 * 35

= 2450 square units

P = 2(70) + 2(35)

= 210 units

The new rectangle is dilated by a 1/5 factor, so both dimensions will be one fifth the size of the original. When you have a scale factor that is 1 over some number, you can find the new measurement by dividing by that denominator.

Therefore, new rectangle's dimensions are:

70 ÷ 5 = 14

35 ÷ 5 = 7

Now, find area and perimeter of the new rectangle.

A = 14 * 7

= 98 square units

P = 2(14) + 2(7)

= 42 units
