Step-by-step explanation:
Area of the two triangles:
divide by 2 to find the other side of the triangle and the radius
this is just one triangle multiply by two to find both sides together
(6)(2) = 12 this is the area of both triangles
Area of the half-circle:
A = this is the formula for a whole circle so we have to then divide by 2
=
= 28.3
=
=
Add the area of the triangle with the area of the half-circle:
12 + 14.13 = 26.13
Hope this helps!!
