The length of the rectangular flower bed is 7 meters and the width is 3 meters less. Calculate the area and perimeter.

The length of a rectangular flower bed is 7 meters.
The width b of the section is 3 meters less than the length a.
Find the width b:
b = a – 3 = 7 – 3 = 4 meters.
We calculate the perimeter of the flower bed by the formula P = a + a + b + b:
P = a + a + b + b = 7 + 7 + 4 + 4 = 22 meters.
Let’s find the area of this piece of land using the formula S = a * b:
S = a * b = 7 * 4 = 28 m2.
Answer: the perimeter is 22 meters, the area is 28 m2.
