A regular heptagon has an apothem of approximately 4.2 ft and a perimeter of approximately 28.0 ft. Find the area of the heptagon.

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

the first 5 right here the next 5 i will upload as separate question

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
