Area of each lateral area = 1/2 * 14* 15 
Total lateral area  ( as it has 3 lateral sides)  = 3 * 1/2 * 14 * 15 =  315 cm^2

Total surface area = 315 * 1/2 * 14 * 15 =  420 cm^2


Hexagonal pyramid

Lateral area = 6 * area of each triangle =  6 * 1/2 *10 * 35 =  1050 cm^2

Total S A = 1050 + area of the hexagonal base =  1050 +  3 sqrt3 10^2 / 2
= 1050 + 259.8 = 1309.8 cm^2

Tina wants to buy grass seed to cover her whole lawn, except for the pool. The pool is 7/12 m by 3 /14 m. Find the area the gras
eimsori [14]

Answer:

Since Tina wants to buy grass seed to cover her whole lawn, except for the pool, and the pool is 7/12 m by 3/14 m, to find the area the grass seed needs to cover the following calculation must be performed:

It is impossible to determine the area that the grass seed needs to cover, because we do not have the data of the total size of the lawn. Now, you can determine the size of the surface that should not be covered, which is the one that the pool occupies, namely:

7/12 x 3/14 = X

0.583333 x 0.2142 = X

0.1249 = X

Therefore, the grass seed should not cover about 0.1249 square meters.
