Plot of rectangular shape adjoins the house, the length of which is 10 meters on 3 sides

Plot of rectangular shape adjoins the house, the length of which is 10 meters on 3 sides, the plot is fenced in length 130 meters What is the area of this plot.

According to the condition of the problem, the site is adjacent to a house, the length of which is 10 meters, which means that one of the sides of the site is 10 meters. And since the site is rectangular, the opposite side is 10 meters.
Since the hedge on three sides of the site is 130 meters long, we find the length of the other two sides:
a = (130 – 10): 2,
a = 120: 2,
a = 60 (m).
Knowing the dimensions of the sides of the site, we calculate its area:
S = a * b = 10 * 60 = 600 (sq. M).
Answer: 600 sq. m.
