Answer:
42.06 ft²
Step-by-step explanation:
2 sides = 2(2.7 ft × 3.2 ft) = 2 × 8.64 ft² = 17.28 ft²
Front + back = 2(2.1 ft × 3.2 ft) = 2 × 6.72 ft² = 13.44 ft²
Top + bottom = 2(2.1 ft × 2.7 ft) = 2 × 5.67 ft² = <u>11.34 ft²
</u>
Total area = 42.06 ft²

2/3 hour=2/3×3600 seconds=2400seconds
It must be noted that the area of the square is calculated through the equation,
A = s²
where A is area and s is the measure of one side of the square.
To determine the measure of one side of the square, we simply have to get the square root of the area,
s = √A
Substituting the known value,
s = √75 ft² = 5√3 ft ≈ 8.66 cm
Thus, the answer to this question is approximately 8.66 cm.
Answer:
Step-by-step explanation:
The xxx-coordinate of BBB is 333 less than the xxx-coordinate of AAA, or 8 - 38−38, minus, 3.
The yyy-coordinate of BBB is 111 greater than the yyy-coordinate of AAA, or -8 + 1−8+1minus, 8, plus, 1.
The coordinates of BBB are (5, -7)(5,−7)left parenthesis, 5, comma, minus, 7, right parenthesis.
