A regular heptagon has sides measuring 26 mm and is divided into 7 congruent triangles. Each triangle has a height of 27 mm. What is the area of the heptagon?

Answers

Answer 1

Answer:

The solution is : 2,457 mm^2, is the area of the heptagon.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

The dimensions of each of the triangles in terms of their bases and heights will be;

26 mm by 27 mm

Mathematically, the area of one of the triangles will be ;

1/2 * base * height

= 1/2 * 26 * 27

= 351 mm^2

So the area of the heptagon is the sum of the areas of all of the triangles

mathematically, that would be;

351 * 7

= 2,457 mm^2

Hence, The solution is : 2,457 mm^2, is the area of the heptagon.

Somebody please help me with this question

Answers

4% of 17000 is 680,

680 *5 = 3400,

3400 + 17000= 20400

the population will be 20400

Hope this helps, and have a nice day

Answer:

20683

Step-by-step explanation:

P(n) is the population at the n th term

17000 is the initial population

R is the grow, which is 4% or .04

Find the population at 5th year

We have :

P(n) = 17000(1+r)^n

P(5) = 17000 (1 +.04)^5

P(5) = 20683.09

Thats a trick question, but I know the answer. You are supposed to divide 20/30. but that doesn't connect with the number. So we move on to 200/30. You multiply 30 by how many will it take to get 200. The answer would be 6.666666666667(hope this will help)
