Answer:
<h2>A = 210 cm²</h2>
Step-by-step explanation:
Area of a parallelogram = base × height
From the question
The base is = 30 cm
Let h represent the height of the parallelogram
We must first use Pythagoras theorem to find the height of the parallelogram before finding it's area
We have

We have the answer as
h = 7 cm
So from the question
height = 7cm
Let's substitute the base and the height into the above formula and solve for the area
We have
Area = 30 × 7
We have the final answer as
<h3>A = 210 cm²</h3>

Answer:
56.72mm
Step-by-step explanation:
BQ = 34 - 16 = 18mm
Using similar triangle,
AQ = QC =(16*18)/34 = 8.47mm
AC = 2*8.47 = 16.94 mm
Since
BC = AB = sqrt( AQ² + BQ²)
BC = AB = sqrt( 8.47² + 18²)
BC = AB = 19.89mm
Perimeter of triangle ABC = AB + BC + AC
P = 19.89 + 19.89 + 16.94
Perimeter = 56.72mm
