On a boat, a cabin's window is in the shape of an isosceles trapezoid, as shown below. What is the area of the window?

An isosceles trapezoid with top side 10 inches long and a longer bottom side. The height is 15 inches. The base of the triangle formed from the height on the right is labeled 3 inches.

The area of the window will be equal to 195 sq. inches.

Step-by-step explanation:

On a boat, a cabin's window is in the shape of an isosceles trapezoid.

The longer side parallel side is at the bottom.

The top side of the trapezoid is 10 inches and the height is 15 inches and the base of the triangle formed from the height on the right is labeled 3 inches.

So, the bottom parallel side has length of (10 + 3 + 3) = 16 inches.

Therefore, the area of the window will be equal to sq. inches. (Answer)

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
