a sailboat has a sail which is shaped like a right triangle. The base of the triangle is 14 feet and the height is 20 feet. What is the area of the sail? The boat also has two smaller sails that are each half as large as the big one. How big is each of the two smaller sails?
triangle area:
A = bh/2
To find the area of the sail, we can use the formula for the area of a triangle, which is given by: Area = (1/2) * base * height.
Given that the base of the triangle is 14 feet and the height is 20 feet, we can calculate the area as follows:
Area = (1/2) * 14 * 20
= 7 * 20
= 140 square feet.
Therefore, the area of the sail is 140 square feet.
Since the two smaller sails are each half as large as the big one, each smaller sail would have an area that is half of 140 square feet.
Area of each smaller sail = (1/2) * 140
= 70 square feet.
Therefore, each of the two smaller sails is 70 square feet in size.
To find the area of the sail, we can use the formula for the area of a triangle:
Area = (1/2) * base * height
In this case, the base is 14 feet and the height is 20 feet. Plugging in these values into the formula, we get:
Area = (1/2) * 14 feet * 20 feet
Simplifying the equation, we have:
Area = 140 square feet
So, the area of the sail is 140 square feet.
Now, let's find the size of each of the two smaller sails. We know that each smaller sail is half the size of the big one. Since the big sail has an area of 140 square feet, each smaller sail will have an area that is half of that.
Area of each smaller sail = (1/2) * 140 square feet
Simplifying the equation, we have:
Area of each smaller sail = 70 square feet
So, each of the two smaller sails is 70 square feet.
