Given:

Given that the irregular figure is broken into a triangle and a rectangle.

We need to determine the length b, the area of the triangle , the area of the rectangle and the area of the irregular figure.

Length of b:

The length of b , the base of the triangle is given by


b=5-(2(1)/(3))

Simplifying, we get;


b=5-(7)/(3)


b=(8)/(3) \ ft

Thus, the length of the base of the triangle is
(8)/(3) \ ft

Area of the triangle:

The area of the triangle can be determined using the formula,


A=(1)/(2)bh

Substituting
b=(8)/(3) \ ft and
h=3 \ ft, we get;


A=(1)/(2)((8)/(3))(3)


A=4 \ ft^2

Thus, the area of the triangle is 4 square feet.

Area of the rectangle:

The area of the rectangle can be determined using the formula,


A=lw

where l = 5 ft,
w=1 (1)/(3)=(4)/(3) \ ft, we get;


A=5 * (4)/(3)


A=(20)/(3) \ ft^2

Thus, the area of the rectangle is
(20)/(3) \ ft^2

Area of the irregular figure:

The area of the irregular figure can be determined by adding the area of the triangle and the area of the rectangle.

Thus, we have;

Area = Area of the triangle + Area of the rectangle

Substituting the values, we have;


Area = 4+(20)/(3)


Area = 10.667 \ ft^2

Thus, the area of the irregular figure is 10.667 square feet.
