Answer:
base: 2/3 ft (Answer C)
Step-by-step explanation:
Recall that the formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
Here A = 2/5 ft^2 = (1/2)(b)(6/5 ft)
We must solve this for b. Start by multiplying all terms by 10 to eliminate the fractions:
10(2/5 ft^2) = (6 ft)(b), or
4 ft^2 = (6 ft)b, or
4 ft^2
b = ---------------- = 2/3 ft (Answer C)
6 ft
Last answer choice because if you divide them the last one gets paid 13 dollars per hour brainlest would be appreciated or even a thanks!!
That is -2.75 or -2 and 3/4 or - 7/4
