A = 73.84
Explanation-
14.2 - 6.4 = 7.8 (to get the length of the base without the top part)
7.8 • 5.2 = 40.56 (to find the area outside of our subtracted square that has the top part)
6.4 • 5.2 = 33.28 (to find the area of the inner square)
40.56 + 33.28 = 73.84 (adding together both parts to find the total area)
A = 73.84
Answer:
7:3
Step-by-step explanation:
Divide both sides by 4
Function: 12+0.5x
12+0.5x=18.5
0.5x=6.5
x=13 days
