Answer:

Length of rectangular lawn =72 meters

Breadth of rectangular lawn =18 meters

Perimeter of rectangle =2(Length+Breadth)

So, Perimeter of rectangle =2(72+18)=2(90)=180 meters

If three shrubs can be planted in a meter of hedge.

Then, Number of shrubs planted in whole perimeter will be=3×180=540

write out the sum using the summation notation, assuming the suggested pattern continues. -10-2+6+14+...+110

Ronch [10]

The series is an arithmetic series with first term -10 and common difference (-2-(-10))=8. The general term a_n can be written as
a_n = -10 + 8(n-1)
or
a_n = -18+8n

The last term corresponds to
110 = -18+8n
128 = 8n
16 = n

So, the summation can be written as
$S_{16}=\sum\limits_{n=1}^{16}{(-18+8n)}$
