On a road, a bike sign in the shape of an isosceles trapezoid is to be painted. The sign and its dimensions are shown below. What is the area of the sign?
9 feet
5 feet
7 feet
(1 point)
35 square feet
40 square feet
50 square feet
55 square
The area of an isosceles trapezoid can be calculated by taking the average of the lengths of the two parallel bases and multiplying it by the height.
In this case, the lengths of the bases are 9 feet and 5 feet, and the height is 7 feet.
Taking the average of the base lengths (9 + 5) / 2 = 14 / 2 = 7 feet.
Then, multiplying the average base length by the height: 7 feet * 7 feet = 49 square feet.
Therefore, the area of the sign is 49 square feet.
So the correct answer is 49 square feet.
