Answer:

The surface area is 286.5in.

Step-by-step explanation:

7.5 * 11.5 = 86.25 * 2 = 172.5in for two big rectangles

7.5 * 3 = 22.5 for little rectangle

11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles

7.5 * 3 = 22.5 for the smallest rectangle

22.5 + 69 + 22.5 + 172.5 = 286.5 in SA

A rectangle has a height of 5 and a width of 4x^2 – 2x – 6.

bogdanovich [222]

The area of the rectangle is $20x^{2} -10x-30$ units.

Step-by-step explanation:

Step 1:

The area of a rectangle is obtained by multiplying the length with the width of the rectangle.

Considering this a whole rectangle, the length of the rectangle is 5 units and the width is the sum of $4x^{2}$ , $-2x$ , and -6.

So the length of the rectangle = 5 units and

the width of the rectangle $= 4x^{2} -2x-6$ units.

The area of a rectangle = (length)(width).

Step 2:

By substituting the known values, we get

The area of the rectangle $= (5) (4x^{2} -2x-6) = 20x^{2} -10x-30.$

So the area of the rectangle is $20x^{2} -10x-30$ units.
