Area of a triangle equals 1/2 Bh
base = 2.5 height = 5
2.5 x 5 = 12.5/2 = 6.25
since there are 4 sides you multiply by 4
6.25 x 4 = 25
Now to do the bottom you multiply 2.5 x 2.5 = 6.25
6.25 + 25 = 31.25<----ANSWER
Hope this helps
Both variables (x) are 3.
4×3=12
12-2=10
16×3=48
48-8=40
3 fits the variable of the missing number.
If you want to know the concept of square roots and cube roots ?
the square root of a number is that number which when multiplied by itself two times gives us that number
e.g.
√64 = x , so that (x)(x) = 64
and from our multiplication table we know that
(8)(8) = 64 , so that
√64 = 8
the cube root of a number is that number which when multiplied by itself three times gives us that number
e.g.
∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64
so ∛64 = 4
