Can u help me find the area ​
kirill115 [55]

Answer:

640 units squared

Step-by-step explanation:

The shape below is a trapezoid.

The formula for the  area of a trapezoid is average of the bases times the height.

The bases are the parallel lines that make up 2 of the sides of the trapezoid.

The height is the line dotted line that creates right angles and is the distance between the two bases.

The bases are 24 and 40.

To find the average, we add them together and divide by 2

(24+40)/2=64/2=32

Now, we multiply 32 by the height, which is given as the length of 20.

32*20=640

the area of the trapezoid is 640 units squared

Hope this helps!

The area of a rug is represented by the following expression, z2 + 4x – 12 , which of the following expressions
ch4aika [34]

Answer:

Width = (x-2)

Step-by-step explanation:

The area of a rug is given by (x^2+4x-12)

The length of the rug is (x+6)

We need to find the width of the rug.

The area of a rug is given by :

A=lb\\\\x^2+4x-12=(x+6)b\\\\b=\dfrac{x^2+4x-12}{(x+6)}\\\\b=\dfrac{x^2+6x-2x-12}{(x+6)}\\\\b=\dfrac{x(x+6)-2(x+6)}{(x+6)}\\\\b=\dfrac{(x+6)(x-2)}{(x+6)}\\\\b=(x-2)

So, the width of the rug is (x-2). Hence, the correct option is (c).
