The diagram shows a rectangle. 0.5 cm 7 cm. Four of these rectangles are put together as shown. Calculate the shaded area

42 cm squared

Step-by-step explanation:

To find the shaded area, we need to find the total area and then subtract the areas of the 4 small rectangles.

The dimensions of the big rectangle are as follows:

- The length is simply the length of one of the small rectangles: 7

- The width is the length of one of the small rectangles plus the width of two of the smaller rectangles, so: 7 + 0.5 + 0.5 = 8

So, the area of the biggest rectangle is 7 * 8 = 56 cm squared.

Now, we need to find the areas of the 4 smaller rectangles. It's just length times width:

7 * 0.5 = 3.5

Multiply by 4 because there are 4 rectangles:

3.5 * 4 = 14 cm squared.

Finally, the shaded area is 56 - 14 = 42 cm squared.

Hope this helps!

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
