HELP ME

Write the formula for the area A of a triangle.
A=

b. Solve the formula for b.

b=

c. Use the new formula to find the base of the triangle.



The base of the triangle is
millimeters.

Please explain and show your work

Answer 1

The area of a triangle formula is A = 0.5*b*h where b is the base and h is the height. To solve for b, we multiply both sides by 2 to get 2A = b*h and then we divide both sides by h to get b = 2A/h. Now plug in the given info to get...

b = 2*A/h

b = 2*36/6

B = 72/6

b = 12

so if the area is 36 and the height is 6, then the the base must be 12
