Yield sign is a triangle and has an area of 10 sq ft. the height is 4ft what is the base length? show your work

To find the base length of the yield sign, we can use the formula for the area of a triangle:

Area = (base x height) / 2

Given:
Area = 10 sq ft
Height = 4 ft

Plugging in the values:
10 = (base x 4) / 2
10 = 2base

Divide both sides by 2:
base = 10 / 2
base = 5

Therefore, the base length of the yield sign is 5 ft.
