A rectangular poster has a length of 72 centimeters and a width of 15 centimeters. The poster is reduced in size by 6 centimeters in length and 3 centimeters in width. What is the area of the new poster?(1 point)
_____ square centimeters
The original area of the poster is:
72 cm * 15 cm = 1080 square cm
After reducing the size by 6 cm in length and 3 cm in width, the new dimensions are:
(72 cm - 6 cm) * (15 cm - 3 cm) = 66 cm * 12 cm = 792 square cm
Therefore, the area of the new poster is 792 square centimeters.
A piece of paper is in the shape of a right triangle. The base is 4.25 inches and the height is 11 inches. What is the area of the right triangle in square inches? Do not round your answer.(1 point)
__ square inches
The area of a right triangle can be calculated using the formula:
Area = (base * height) / 2
Given that the base is 4.25 inches and the height is 11 inches, we can plug these values into the formula:
Area = (4.25 in * 11 in) / 2
Area = (46.75 in^2) / 2
Area = 23.375 square inches
Therefore, the area of the right triangle is 23.375 square inches.
What is the area of the non-right triangle? The base and height are found by counting the squares.
(1 point)
The area is
__ square units
To calculate the area of a triangle, you can use the formula:
Area = (base * height) / 2
Given that the base is 4 units and the height is 8 units (as we count the number of squares), we can plug these values into the formula:
Area = (4 units * 8 units) / 2
Area = (32 square units) / 2
Area = 16 square units
Therefore, the area of the non-right triangle is 16 square units.
What is the area of the quadrilateral?
(1 point)
__ in.2
To calculate the area of a quadrilateral, we can break it down into two triangles and then calculate the sum of the areas of these triangles.
1. Triangle 1:
Base = 6 units
Height = 3 units
Area of Triangle 1 = (base * height) / 2
Area of Triangle 1 = (6 units * 3 units) / 2
Area of Triangle 1 = 9 square units
2. Triangle 2:
Base = 2 units
Height = 3 units
Area of Triangle 2 = (base * height) / 2
Area of Triangle 2 = (2 units * 3 units) / 2
Area of Triangle 2 = 3 square units
Total Area of the Quadrilateral = Area of Triangle 1 + Area of Triangle 2
Total Area of the Quadrilateral = 9 square units + 3 square units
Total Area of the Quadrilateral = 12 square units
Therefore, the area of the quadrilateral is 12 square units.

I'm sorry, but I need more information or context to determine the area of the polygon. The area of a polygon depends on the number of sides, the length of each side, and sometimes the measure of angles. If you can provide additional details or measurements, I would be able to calculate the area for you.
