Answer:
JK = 24
Step-by-step explanation:
Δ BKJ and Δ BCA are similar triangles and ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
5JK = 120 ( divide both sides by 5 )
JK = 24
We have a parallelogram and a half of circle.
<h3> The area of parallelogram are: A=basis*height</h3><h3>The area of circle are: A=πr², where r is the radius (half of diameter). Thus the half circle have Area equals to:</h3>Approaching π to 3,14
parallelogram:
b=26
h=13
A=13*26
A=338
Half circle:
r=12
A=(3,14*12²)/2
A=226,08
<h2>Total Area of the figure are:</h2><h2>A=338+226,08</h2><h2>A=564,08</h2>
