The height of the building to the nearest tenth of a meter is; 13 m
<h3>How to make use of Cosine Rule?</h3>
The slant line from the top of Trevor's head to the base of the building is gotten from Pythagoras theorem;
15/x = sin 36°
x = 15/sin 36
x = 25.52 m
Angle between that slant line and base of building is;
90 - tan⁻¹(1.5/14) = θ
θ = 83.88°
Remaining angle of the bigger triangle is;
180 - (36 + 83.88) = 60.12°
Thus, if the height of the building is h, then;
h/sin 36 = 25.52/sin 60.12
h = 13 m

Answer:
Parimeter = (10 2/3 + 6 1/4 + 10 2/3 + 6 1/4) = 20 4/3 + 12 2/4
Parimeter = 21 1/3 + 12 1/2 = 21 2/6 + 12 3/6 = 33 5/6 ft
Amount of Wallpaper Border = 33 5/6 ft
