Answer:

Step-by-step explanation:

If perimeter is 28 then each side is 28/7=4ft These sides can be seen as the bases of seven triangles that make up the heptagon. The apothem, 4.2ft, is the height of each of those triangles. The total area will be the sum of the areas of those seven triangles.

A=7(bh)/2

A=(7(4)4.2)/2

A=58.8 ft^2

A sum of money is divided in the ratio 2 : 3 : 7 .Given the largest share is $112,calculate the smallest share.

emmasim [6.3K]

Answer:

$32

Step-by-step explanation:

A sum of money is divided in the ratio 2:3:7.

Let the share of each individual be represented by 2x,3x,7x respectively.

The largest share (7x) is given as $112.

$7x = 112$

$=>x = \frac{112}{7}$

$=>x = 16$

So the respective shares are $2\times16,3\times16,7\times16$

In other words, the shares are 32,48,112.

So the smallest share is $32
