Find the missing value for the following triangles:
Base: Height: Area:
27in. 54in.^2
4cm 64cm^2
It is not clear from your table which value is missing.
Just use the relationship
Area = (1/2) (base) x (height)
and figure it out for yourself.
area=base x height
You have to use the relationships
base=area/height
height=area/base
ok thanks
To find the missing value for the triangle, we can use the formula for the area of a triangle, which is given by:
Area = (1/2) * base * height
Case 1: Missing Base
If the base is missing, we can rearrange the formula to solve for the base:
base = (2 * Area) / height
For the first triangle with an area of 54in² and a height of 27in, we can calculate the missing base as follows:
base = (2 * 54in²) / 27in
base = 108in² / 27in
base = 4in
So, the missing value for the first triangle is 4in for the base.
Case 2: Missing Height
If the height is missing, we can rearrange the formula to solve for the height:
height = (2 * Area) / base
For the second triangle with an area of 64cm² and a base of 4cm, we can calculate the missing height as follows:
height = (2 * 64cm²) / 4cm
height = 128cm² / 4cm
height = 32cm
So, the missing value for the second triangle is 32cm for the height.
