Answer 1

Answer:

The base of the logo must be less than 6 feets but greter than 0 feet, 0<b<6.

Step-by-step explanation:

The formula of area of triangle is A = 1/2×b×h where b is the base and h is the height. It is given that the height of the logo is 4ft and the area is lesa than 12 ft². Using this information, we can make an inequality exrpression :

Let h = 4ft

1/2 × b × 4 < 12

1/2 × b < 12 ÷ 4

1/2 × b < 3

b < 3 ÷ 1/2

b < 6 ft
