Answer:
A) 88 mm; 415.7 mm^2
Step-by-step explanation:
The given figure is parallelogram. This means that the opposite sides are congruent. From the information given, the sides are 20mm and 24mm. Since the opposite sides are congruent, the other sides would be 20mm and 24mm as well
Perimeter = sum of the sides
Thus,
Perimeter = 20 + 20 + 24 + 24
Perimeter = 88 mm
The formula for calculating the area of the parallelogram is expressed as
Area = base x height
From the diagram,
base = 24
height = 17.32
Area = 24 x 17.32
Area = 415.7 mm^2
