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
Answer:
Step-by-step explanation:
12
This is what we call a 45-45 traingle
This means that the lengths of the two non-hyptonouse lengths are the same
luckily we're given that it's 6√2
We can then use the pathagaryem theory to solve for the last side
we have
(6√2)²+(6√2)²=x²
Put this into your calculator and get
144= x²
x = 12
