1. The condition of the problem is a rectangle.
It is known that the length of the figure is 70 cm.
The width of the rectangle is not explicitly set, but it is said to be 70% or 70/100 = 7/10 of the length.
Let’s calculate the width.
70 * 7/10 = 49 cm.
2. Now you can calculate the area of the given rectangle.
It is determined by the product of its length and width.
S = 70 * 49 = 3430 cm2.
3. Find the perimeter of the shape.
It is found by doubling the sum of the length and width.
P = 2 * (70 + 49) = 2 * 119 = 238 cm.
Answer: The area of the rectangle is 3430 cm2, the perimeter is 238 cm.
