The rectangle is 2.4 m long and 60% wide. Find the area of the rectangle.

Given:
The length a of the rectangle is 2.4 meters.
The width b of the figure is 60% of its length a.

Let us find using the proportion the value of the width b:
2.4 meters – 100%
b – 60%
b = 60 * 2.4: 100 = 1.44 meters.
We calculate the area of the rectangle using the formula S = a * b:
S = a * b = 2.4 * 1.44 = 3.456 m2.
Answer: S = 3.456 m2.
