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
