Expert Solution & Answer
Check Mark
To determine

Area of given figure round to 2 decimal places.

Answer to Problem 1A

Area of given figure is 11.62in.2.

Explanation of Solution

Given:

  Mathematics for Machine Technology, Chapter 58, Problem 1A , additional homework tip  1

  l1=0.418in.

  b1=3in.

  l2=15in.

  b2=0.524in.

  b3=0.416in.

  h=3in.

The shaded diagram is represented as:

  Mathematics for Machine Technology, Chapter 58, Problem 1A , additional homework tip  2

The above diagram is divided into three parts.

The area of diagram can be calculated as:

  A=2A1+A2+2A3 ... Eq. (1)

Now

  A1=l1b1

  A1=(0.418×3)in.2

  A1=1.254in.2

Then

  A2=l2b2

  A2=(15×0.524)in.2

  A2=7.86in.2

Then

  A3=12b3h

  A3=12(0.416in.)(3in.)

  A3=0.624in.2

Substitute the values of A1, A2 and A3 in Eq. (1)

  A=2A1+A2+2A3

  A=2(1.254in.2)+(7.86in.2)+2(0.624in.2)

  A=11.62in.2

Therefore, the area of given figure is 11.62in.2.
