To solve this problem, we can use cross multiplication:
First, we can to convert inches into feet so...
5 inches = 0.416667 ft
7 inches = 0.583333 ft
(0.416667 ft/ 0.583333 ft) = (12 ft/ x ft)
x = 16.8 ft
So the actual width is 16.8 ft.
Hope this helps!
Let height of house be x.
Oak tree = 120 + x
Also given,
Oak tree = 2.5x
120 + x = 2.5x
1.5x = 120
0.3x = 24
3x = 240
x = 80
Hence, the height of the house is 80 ft.
