What is the formula for finding the area of a triangle?
Right.
isnt the area of a triangle .5bh?
To find the area of a triangle given the base and altitude, you can use the formula:
Area = (1/2) x Base x Altitude
Given that the base is 7ft and the altitude is 15ft, we can substitute these values into the formula:
Area = (1/2) x 7ft x 15ft
Let's calculate this:
Area = 0.5 x 7ft x 15ft
Area = 52.5 ft^2
Therefore, the correct answer to the nearest tenth is 52.5 ft². So, the answer would be (a) 52.5 ft².
