Answer:
The building is 76 feet tall
Step-by-step explanation:
Since the tree is halfway beween the stake and the building, then if D is the distance between the building (at ground level) and the stake, then the tree forms with the stake a rectangle triangle with base length equal to D/2 and Height equal to 38 feets.
The stake and the top of the buidling also form a triangle rectangle with base length equal to D. Since rectangle triangle preserve proportions, if we double the length of the base without changing the angle, then the heigth should also be doubled, and as a consecuence, the height of the building is 38*2 = 76 feets.
area of rectangle = L x W
area = 2 * 1.25 = 2.5 square meters
cutting along the diagonal makes a triangle
area = 1/2 x 2.5 = 1.25 square meters
