Area = 1/2bh
Area = 144
Base = 24 (2 ft converted to inches)
144 = 1/2*24*h
h = 12 inches = 1 ft

area of the triangle= 144 sq inches
two of these make a rectangle with an area of 288 sq inches
area of a rectangle= length x width
288 sq inches= 24 inch x altitude of the triangle or width of rectangle
288/24=12 inches
altitude = 12 inches or 1 ft

In geometry, an altitude of a triangle is a straight line through a vertex and perpendicular to (i.e. forming a right angle with) the opposite side or an extension of the opposite side. The intersection between the (extended) side and the altitude is called the foot of the altitude. This opposite side is called the base of the altitude. The length of the altitude is the distance between the base and the vertex.
The length of the altitude is 12 inches, but, you didn't ask that.

The area of a triangle is ½baseXaltitude. The area is 144 square inches = 1 square foot. Therefore, 1 = ½(2)Xaltitude.
1 = 1X altitude. Therefore, 1 = altitude.

A= 1/2 base times height, so, multiply the area times 2 and divide that by 24 (the base in inches) Height= 12 in or 1 ft

12 inches bcause area of a triangle is 1/2 b*h so multiply the triangles area by 2 and divide by given leg

Let me walk you thru this...if you draw the triangle, then draw a line down the center to divide in half, you can take either half and rotate it 180 degrees. You've now made a square 12 inches wide and 12 inches tall. 12x12=144 square inches. Your answer is "twelve inches tall".

A=(1/2)bh So 144=(1/2)(2)h Thus the altitude would be 144in

If it were a rectangle the area would be 288 sq. in.
Therefore the altitude would be 288 divided by 24 (2 ft) = 12 inches (one foot)
