Each side of the square would be 80/4 = 20 cm. so its area = 20^2 = 400 cm^2.
Th rectangle will have perimeter = 80 = 2x + 2(x - 12) where x = height of the rectangle
4x = 80+24 = 104
so x = 26
area of rectangle = 26*(26-12) = 364 cm^2
Answer:
-4
Step-by-step explanation:
if you switch it you get 12-16 and you have to get a negative so 16-12 is 4 so switch it to a nrgative to get -4
It doubles the answer so if your sum is 2 it will become 4
The answer should be ................... 100
Answer:
Part A) Option C. obtuse
Part B) Option B. acute
Step-by-step explanation:
we know that
Applying the Pythagoras Theorem
if ----> is a right triangle
if ----> is an obtuse triangle
if ----> is an acute triangle
where
c is the greater side
Part A) A triangle has side lengths 32, 45 and 18. What type of triangle is it?
we have
therefore
Is an obtuse triangle
Part B) A triangle has side lengths 44, 36 and 30. What type of triangle is it?
we have
therefore
Is an acute triangle
