Hi there!

Find the perimeter using the formula:
P = 2l + 2w
It is given that the dimensions are 2.8 × 1.9 so plug these number into the equation:
P = 2(2.8) + 2(1.9)
P = 5.6 + 3.8
P = 9.4m
Answer: 19.2 inches would be the most reasonable answer, since the first two is too small, and the last answer would be too tall.
if there was 2 feet of water, it would be 24 inches full. taking 1 gallon out, wouldn't make the difference to make it go up or down much.
X^2 = 4^2 - (2√3)^2
x^2 = 16 - 12
x^2 = 4
x = 2
answer
x = 2 cm
So, the right option is 1. so if my ans was helpful u can follow me.
