It took James 5h to paint an 8ft by 24ft wall. At this rate, how long would it take him to paint a 12ft by 36ft wall

1 answer:

3 0

8 * 24 feet = 192 sq feet per 5 hours

12* 36 = 432 square feet

432 is 2.25 times the area of 192 square feet

So, it takes 5 * 2.25 = 11.25 hours

zhuklara [117]

Answer:

$4.50\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC

$cos(A)=\frac{AC}{AB}$ -----> the cosine is the adjacent side to angle A divided by the hypotenuse

substitute the values and solve for x

$cos(68\°)=\frac{x}{12}$

$x=12*cos(68\°)=4.50\ ft$
