The area of the rectangle is 875 cm2 and its length is 35 cm, the perimeter of the rectangle.

S = 875 cm².

a = 35 cm.

b =?.

P =?.

The area of a rectangle is determined by the formula:
S = a * b.

You can express the width, for this product we divide by the first factor (length):

b = S: a.

Substitute the values from the condition and write the expression:

b = 875: 35 = 25 cm.

The sum of all sides of such a figure (perimeter) is calculated by the formula:
P = 2a + 2b = 2 * 35 + 2 * 25 = 70 + 50 = 120 cm.
