A rectangular heptagon is measuring 26 mm and is divided by 7 congruent triangles. Each triangle has a height of 27 mm. What is
alina1380 [7]

Answer:

2,457 mm^2

Step-by-step explanation:

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

Pls help I need a good grade

It was about dusk, one evening during the supreme madness of the carnival season, that I encountered my friend. He accosted me with excessive warmth, for he had been drinking much. The man wore motley. He had on a tight-fitting parti-striped dress, and his head was surmounted by the conical cap and bells. I was so pleased to see him, that I thought I should never have done wringing his hand.
 

I said to him—"My dear Fortunato, you are luckily met. How remarkably well you are looking to-day! But I have received a pipe of what passes for Amontillado, and I have my doubts."
 

"How?" said he. "Amontillado? A pipe? Impossible! And in the middle of the carnival!"
