The perimeter of a triangle is the sum of its side lengths.
The perimeter of the triangle is:
<u>The sides of the triangle are:</u>
Side 1 = (8d - 3) cm
Side 2 = (6d + 2) cm
Side 3 = (7f + 8) cm
The perimeter (P) is calculated as:
P = Side 1 + Side 2 + Side 3
So, we have:
Remove brackets
Collect like terms
Hence, the perimeter of the triangle is:

Answer:
Options (B) and (E)
Step-by-step explanation:
Area of ΔABC =
=
= 42 in²
Area of trapezoid ADEC =
[Here, and
are the parallel sides and 'h' is the height of the isosceles trapezoid given]
=
= 96 in²
Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC
= 42 + 96
= 138 in²
Therefore, Options (B) and (E) are the correct options.
