Find the area of a right triangle with base of 10 centimeters and a height 7.4 centimeters.(1 point)Responses37 square centimeters37 square centimeters17.4 square centimeters17.4 square centimeters74 square centimeters74 square centimeters34.8 square centimeters34.8 square centimeters
Area = 0.5 * base * height
Given that the base is 10 centimeters and the height is 7.4 centimeters, we can plug these values into the formula:
Area = 0.5 * 10 * 7.4
Area = 0.5 * 74
Area = 37 square centimeters
Therefore, the correct response is: 37 square centimeters.

Area = 0.5 * base * height
Given that the base is 15 centimeters and the height is 5 centimeters, we can plug these values into the formula:
Area = 0.5 * 15 * 5
Area = 0.5 * 75
Area = 37.5 square centimeters
Therefore, the correct response is: 37.5 square centimeters.
A piece of a tile is in the shape of a right triangle. The base is 1 1/2 centimeters and the height is 2 1/2 centimeters. What is the area in square centimeters?(1 point)Responses4 square centimeters 4 square centimeters8 square centimeters 8 square centimeters178 square centimeters1 Start Fraction 7 over 8 end fraction square centimeters334 square centimeters
Area = 0.5 * base * height
First, convert the mixed numbers into improper fractions:
Base: 1 1/2 = 3/2
Height: 2 1/2 = 5/2
Now, apply the formula:
Area = 0.5 * 3/2 * 5/2
Area = 0.5 * 3/2 * 5/2
Area = 0.5 * 15/4
Area = 15/8
Area = 1 7/8 square centimeters
Therefore, the correct response is: 1 Start Fraction 7 over 8 end fraction square centimeters.
