The area of a rectangle (S) is equal to the product of its length (a) and width (b):
S = a * b.
Knowing the area and one of the sides of the rectangle, you can find its second side:
a = S: b,
b = S: a.
Let’s calculate the length of the rectangle, the area of which is 136 cm2, and the width is 8 cm:
a = 136: 8,
a = 17 cm.
Answer: the length of the rectangle is 17 cm.
