Introduction to area of a piecewise rectangular figure
stich3 [128]

Given:

The piecewise rectangular figure.

To find:

The area of the piecewise rectangular figure.

Solution:

Draw a line and divide the given figure in two parts (a) and (b) as shown in the below figure.

Figure (a) is a rectangle of length 5 yd and width 3 yd. So, the area of the rectangle is:

Area=length\times width

A_a=5\times 3

A_a=15

Figure (b) is a square of edge 2 yd. So, the area of the square is:

Area=(edge)^2

A_b=(2)^2

A_b=4

The area of the given figure is:

A=A_a+A_b

A=15+4

A=19

Therefore, the area of the given figure is 19 square yd.
