Answer:
height = 4.8 cm
area = 120 cm²
perimeter = 62 cm
Step-by-step explanation:
<u>**Please refer to the attached diagram when following the step-by-step**</u>
First, find m∠C (green angle on diagram) by using the cosine rule:
Therefore, the interior angle of the right triangle at point C (blue angle on diagram) is:
Now use the Sine Rule (for finding sides) to determine height (h):
So the height = 4.8 cm
Now we have determined the height, we can calculate the area by using the area of a parallelogram formula:
Area of a parallelogram = base x perpendicular height
⇒ area = 25 x 4.8 = 120 cm²
Parallelogram is a four-sided shape made up of two pairs of straight parallel lines that are equal in length.
Perimeter = sum of the sides
⇒ perimeter = 6 + 6 + 25 + 25 = 62 cm
