MATH HELP! How to determine height when given area and base

[From: ] [author: ] [Date: 12-04-18] [Hit: ]
-given this: 40= 1/2 (10 x h),h = 8-I assume were talking triangles here.2A / b = h,For this specific question,h = (2 x 40) / 10 = 8-You dont even mention a shape but I am assuming its a triangle.If yes,......
When given 40 as the area and the base is 10 whats the height?

40= 1/2 (10 x h) I know it 80, but how is it determine?

given this: 40= 1/2 (10 x h),
i'm assuming that the shape is a triangle

area of a triangle:
A = (1/2)bh
A = 40
b = 10

A = (1/2)bh
40 = (1/2)(10)(h)
40 = 5h
h = 40/5
h = 8

I assume we're talking triangles here.

The area formula A = bh/2 needs to be rearranged to make h the subject:

2A = bh

2A / b = h, or

h = 2A / b

For this specific question,

h = (2 x 40) / 10
= 8

You don't even mention a shape but I am assuming its a triangle.

If yes, then Area = 1/2 * base & height

Height = Area * 2 / base
Height = 8 cm
