| To find the perimeter of a rectangle, fold the 4 sides of the rectangle.
P = a + b + a + b.
a = 70 cm.
b = 70 * 7/10 cm = 49 cm.
Now let’s calculate the perimeter of the rectangle:
P = 70 cm + 49 cm + 70 cm + 49 cm = 238 cm.
The area of a rectangular area is found by multiplying the length and width of the rectangle:
S = a * b.
S = 70 cm * 49 cm = 3430 cm2.
Answer: The perimeter of the rectangle is 238 centimeters, and the area is 34340 square centimeters.
