To solve this problem you first need to establish what it is you are looking for.. if you knew the grandson age then you could find your son and you. So that is what we need to find and since we don't know it, we will call it x.
Grandson = x
Son = 7x
You = 12x
Then it says the sum of the 3 is 100.... x + 7x + 12x = 100 then solve and find that x = 5. So to determine your age, just put 5 in for x and you get 60... dang your old ha

Answer:
I know it's not the answer ur looking for but [mathaway] will help u ace ur test
This problem can be completed in 2 ways. Both are acceptable.
Option 1:This is an isosceles trapezoid that can be divided into a rectangle and two congruent triangles.
The area of the rectangle is the base times the height.
The area of one of the triangles is half the base times the height.
The other triangle must have that area too.
The area is 56 square centimeters.
Option 2:We can use the area formula for the trapezoid.
Where
is the length of the shorter base
and
is the length of the longer base
and
is the height.
The length of the shorter base is 9.
The length of the longer base is 9+5+5, or 19.
The height is 4.
Same answer. The area is 56 square centimeters.
Both options are two acceptable ways the problem can be tackled.
