The area of the triangle is 10 and the semicircle is 39.25
The total area is 49.25cm²
Step-by-step explanation:
Triangle area:
A=(b•h)/2
A=(10•2)/2
A=20/2
A=10
Semicircle area
A=(π•r²)/2
π=3.14 and r=5
A=[3.14•(5²)]/2
A= (3.14•25)/2
A=78.5/2
A=39.25
Area total
At= triangle area+semicircle area
At=39.25+10
At=49.25cm²
