Area and algebra grade 7

Question

If the area of a triangle is 180, and the base is 8, what is the height?

Answer 1

The area of a triangle is represented by the equation:

Area = (1/2) (B) (H)

B represents the base and H represents the height.

If the area is 180, and the base is 8, we can plug them into our equation and solve for H (height):

180 = (1/2) (8) (H)

Simplify the right side and we have:

180 = 4H

Isolate the H by dividing by 4 on each side and we get:

45 = H

The height of the triangle is 45.
