The figure has been decomposed into three rectangles as shown.
A figure is decomposed into 3 rectangles. The rectangles are 4 inches by 2 inches, 6.5 inches by 2 inches, and 4 inches by 1.5 inches.
Find the area of each piece of the composite figure.
The area of the top rectangle is
A = 4 in.(2 in.) = 8 in2.
The area of the middle rectangle is
A = 2 in.(
in.) =
in2.
The area of the bottom rectangle is
A = 4 in.(
in.) =
in2.
The total area of the figure is
in2.
hi
To find the area of a rectangle, you multiply its length by its width.
For the top rectangle:
A = 4 inches * 2 inches = 8 square inches.
For the middle rectangle:
A = 6.5 inches * 2 inches = 13 square inches.
For the bottom rectangle:
A = 4 inches * 1.5 inches = 6 square inches.
To find the total area of the figure, you add up the areas of the individual rectangles:
Total area = 8 square inches + 13 square inches + 6 square inches = 27 square inches.
To find the area of each piece of the composite figure, we need to multiply the length and width of each rectangle.
For the top rectangle, the length is 4 inches and the width is 2 inches. To find the area, we multiply the length by the width:
Area = 4 in. * 2 in. = 8 in^2
So the area of the top rectangle is 8 square inches.
For the middle rectangle, the length is 6.5 inches and the width is 2 inches:
Area = 6.5 in. * 2 in. = 13 in^2
So the area of the middle rectangle is 13 square inches.
For the bottom rectangle, the length is 4 inches and the width is 1.5 inches:
Area = 4 in. * 1.5 in. = 6 in^2
So the area of the bottom rectangle is 6 square inches.
To find the total area of the composite figure, we add up the areas of all three rectangles:
Total Area = 8 in^2 + 13 in^2 + 6 in^2 = 27 in^2
So the total area of the figure is 27 square inches.
you did the first one.
what makes the others a problem?
area = length * width
