Answer:
Step-by-step explanation:
a) area of the rectangle = length × breadth
Therefore area should be = 12cm × 6cm
Which should give you the answer 72centimetre squared.
b) area of triangle A = 1/2 × b × h
So that is 1/2 × 3 × 6
Which is 18 centimetres × 1/2
Which is 9 centimetres squared
c) area of triangle B = 1/2 × b × h
So 1/2×3×6=18
Now 1/2×18 should give you 9 centimetres squared
d) therefore the area of the parallelogram = 72+9+9=90 centimetres squared
Therefore the area of the parallelogram is 90 centimetres squared
3.2=x______________________________
2x + 3x + 5x = 180
10x = 180
x = 18
2x = 36, 3x = 54, 5x = 90
They add up to 180 (definition of sum of angles of a triangle.)
Answer:
b-2=n
Step-by-step explanation:
So, we know the center is at -1, -3, hmmm what's the radius anyway?
well, the radius will be the distance from the center to any point on the circle, it just so happen that we know -7, -5 is on it, thus
