The two rectangular forest sites have the same area. The width of the first section is 8 km, and the second is 6 km, find the length of the first section, if the length of the second is 12 km.
The task:
width of the first section b1 – 8 km,
width of the second section b2 – 6 km,
the length of the first section a1 -? km,
the length of the second section a2 – 12 km,
S1 = S2.
Decision:
1) define the area of the plots:
S1 = S2 = a2 b2 = 6 12 = 72 m ^ 2;
2) calculate the length of the first section:
a1 = S1: b1 = 72: 8 = 9 m.
Answer: the length of the first section is 9 meters.
