Answer:

Note that surface is a triangle of base 3.14 * 14.8 = 46.6 cm

B / 2 = 23.2 cm     1/2 base

the height of triangle = 10 cm

A = 23.2 * 10 = 232 cm     the area of the surface

Area formulas provides

A = Π r (r^2 + h^2)^1/2 which is the same as above

The quantity in brackets is just the slant height of 10 cm

  1. To divide the triangles into these regions, you should construct the <u>perpendicular bisector</u> of each segment.
  2. These perpendicular bisectors intersect and divide each triangle into three regions.
  3. The points in each region are those closest to the vertex in that <u>region</u>.

<h3>What is a triangle?</h3>

A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.

<h3>What is a line segment?</h3>

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

<h3>What is a perpendicular bisector?</h3>

A perpendicular bisector can be defined as a type of line that bisects (divides) a line segment exactly into two (2) halves and forms an angle of 90 degrees at the point of intersection.

In this scenario, we can reasonably infer that to divide the triangles into these regions, you should construct the <u>perpendicular bisector</u> of each segment. These perpendicular bisectors intersect and divide each triangle into three regions. The points in each region are those closest to the vertex in that <u>region</u>.

10.) Part A: What is the area, in square feet, of the kitchen?
just olya [345]

The computation shows that the area of the kitchen that's in the home in square feet is 50ft².

<h3>How to calculate the area?</h3>

It should be noted that an area of a rectangular space is calculated by multiplying the length by the width.

In this case, the area of the kitchen will be:

= 5ft × 10ft

= 50ft²
