A. 14 square units
Hey there :)
Well let's find the area of each individual rectangles.
Let's start with the side rectangle.
It has dimensions of 5*1 = 5.
5 square units
Now the 3 rectangles left have dimensions of 3*1=3,
3*3 = 9.
14 square units
A, 14 square units
What I would do is separate them into 4 shapes like the picture below
Because all of the shapes are rectangles, you can use the formula
For shape #1, the length is 1 and the width is 3. Plot the numbers
Multiply 1 by 3 to get
The area of shape #1 is 3
The length and width of shape #2 and 3 are the same as 1, so you can multiply the area of shape #1 by 3 to get
The area of shape #1, 2, and 3 are 9.
Next, you want to find the area of shape #4 which has a length of 5 and a width of 1.
Use the same formula to get
Multiply 5 by 1 to get
The area of shape #4 is 5
The way to find the surface area of the whole figure is to add the area of all the shapes individually, or do what I did and add 5, to 9
This gives you your answer which is
Hope this helps.
Feel free to ask any more questions if you are confused.
Have a great day! :)
14cm² is the area of the shaded region
recognize that those two small triangles plus that arc area is equal to 1/4 of the area of the circle.
56 / 4 = 14cm
the answer is B
The anwser is letter A
