6
Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is
our base and height are 6 for both triangles, so we shall find the area of one of the triangles...
multiply this by 2
Now find the area of the whole circle
our radius is 6, therefore:
Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer
Step-by-step explanation:
5 + 4(x - 2)
5 +4x -8
= 4x - 3
Answer:
B
Step-by-step explanation:
- divide the given polygon into two (a square and a trapezium
- area of trapezium=1/2(a+b)×b 1/2(12+6)×12 ans 108square unit
- area of a square=s×s 12×12 =144square unit
- add 108+144=252square unit
