Question

The area of a sail is 40 1/2 square feet. The base and the height of the sail are equal. What is the height of the sail (in feet)?

Answer 1

Answer:

Height of the sail is 9 feet.

Step-by-step explanation:

Since sail is in the shape of a triangle and the formula of a triangle is

Area = (1/2)×Base×Height

Area of the sail has been given in the question and we have to calculate the height of the sail.

40.5 = (1/2)× Height× Height ( since base = height)

40.5×2 = height² = 81

height = √81 = 9 feet.

Answer 2

Both base and height of the sail is 40 1/2 feet.

A sail is triangular in shape. Finding the area of a triangle is multiplying its base and height and dividing the product by 2.

A = 1/2 bh

Area = 40 1/2 or 40.50 sq. ft
Since base and height are equal.
40.50 x 2 = 81
bh = 81
bh = 81 ÷ 2
b = 40 1/2 ft
h = 40 1/2 ft
