Can someone plz help me with this 1 question and work shown plz

Using the formula for the area of a triangle, , write an expression for the area of ΔABC. Base your answer on the work you did i

Montano1993 [528]

Answer:

$Area = \frac{1}{2} * AC * D$

Step-by-step explanation:

From the complete question, we have:

Length D to be perpendicular to side AC

So, the area of the triangle is:

$Area = \frac{1}{2} * Base * Height$

Since:

Length D is perpendicular to side AC

Then:

$Base = AC$

$Heigjt =D$

So:

$Area = \frac{1}{2} * AC * D$

Find the surface area of the composite figure.

Sloan [31]

With the help of the area formulae of rectangles and triangles and the concept of surface area, the surface area of the composite figure is equal to 276 square centimeters.

<h3>What is the surface area of a truncated prism?</h3>

The surface area of the truncated prism is the sum of the areas of its six faces, which are combinations of the areas of rectangles and right triangles. Then, we proceed to determine the surface 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 area formulae of rectangles and triangles and the concept of surface area, the surface area of the composite figure is equal to 276 square centimeters.
