Length X Width =
2 x 7 = 14
2/9 x 7 = 44/9
14 + 44/9 = 18 8/9
He has 18 8/9 feet left to tile.
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.
<h3>What is the surface area of a truncated prism?</h3>
The <em>surface</em> area of the <em>truncated</em> prism is the sum of the areas of its six faces, which are combinations of the areas of rectangles and <em>right</em> triangles. Then, we proceed to determine the <em>surface</em> area:
A = (12 cm) · (4 cm) + 2 · (3 cm) · (4 cm) + 2 · (12 cm) · (3 cm) + 2 · 0.5 · (12 cm) · (5 cm) + (5 cm) · (4 cm) + (13 cm) · (4 cm)
A = 48 cm² + 24 cm² + 72 cm² + 60 cm² + 20 cm² + 52 cm²
A = 276 cm²
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.

Answer:
1k or k
Step-by-step explanation:
Lets solve the problem without k. The problem would be -6+7. The answer is 1. Then we add the k at the end.
We get 1k, which can be written as just k.
Answer:
The distance of the ship from the cliff is 38.465 feet
The height of the cliff is 46.28 feet.
Step-by-step explanation:
As shown in the figure attached 
is the distance from the ship to the cliff, and 
is the height of the cliff from the ship.
From trigonometry
This is the distance to the cliff.
And we have
since 
Ad the height of the cliff is just 
or
Which is the height of the cliff.
