The area of the window is 182 square inches.
Option: B.
<u>Step-by-step explanation:</u>
From the given data, we are given with the length of the upper side of the trapezoid, the right side's bottom excluded the length upper side's length and height of the trapezoid.
Area of an isosceles trapezoid = ( a+b) h.
where a is the length of upper side of the trapezoid, b is the length of lower side of the trapezoid and h is the height of the trapezoid.
a= 12 inches.
h= 13 inches.
We are given only with the right side's length of base excluding the length of upper side.
So we have to calculate b= left side + upper side+ right side.
b= 2+12+2.
b= 16 inches.
Area of an isosceles trapezoid = (12+16)(13).
= (28)(13).
= 14(13).
= 182 square inches.
∴ Area of the window= 182 square inches.
Mental way:
415 / 51.9 * 100 = 800 students in the school.
detailed way:
x is the amount of students in the school.
51.9% * x = 415
(divide both sides by 51.9% (or 0.519))
x = 800 students
4 1/4 can be rewritten in improper form as: 17/4
because 4 1/4 = 4/4 + 4/4 + 4/4 +4/4 + 1/4 = 17/4
Since the water level drops, you could represent that as a negative number as well. So another possible answer is - 17/4.
Answer:
A = 26.66 ft^2
Step-by-step explanation:
Recall, please, that the formula for the area of a triangle of base b and height h is
A = (1/2)(base)(height).
Here,
A = (1/2)(8.6 ft)(6.2 ft) = 26.66 ft^2, or 26 2/3 ft^2.
