Transplants 29961

In the middle of the square, they created a flower bed in the shape of an isosceles trapezoid. The parallel sides are 12 m and 8 m long. The bed is 6 m wide. How many flower transplants do they need to plant a flower bed if 4 dm2 of space must be counted per transplant?

Correct answer:

n =  1500

Step-by-step explanation:

a=12 m b=8 m h=6 m  S=2a+b h=212+8 6=60 m2 S1=4 dm2 m2=4:100  m2=0.04 m2  n=S/S1=60/251=60:251=60 125=160 25=11500=1500
