840 in (12 x 2 x (20 + 15))
Perimeter = 20+20+15+15 = 70 feet

20ft * 15ft = 300 square feet.
Let x= height of the tree By ratio and proportion: 6ft/4.5ft = x/15ft 4.5ft x = 6ft (15ft) x= 20ft.

Perimeter = 20+20+15+15 = 70 feet
Perimeter l+l+w+w= 70ft Area LxW =300 sqft
It is 60 feet.

20ft * 15ft = 300 square feet.
20ft is the perimeter.
20ft
Let x= height of the tree By ratio and proportion: 6ft/4.5ft = x/15ft 4.5ft x = 6ft (15ft) x= 20ft.
Divide the perimeter by 4, to get the length of one side. From there, you can easily calculate the area.
5ft x 4 = 20ft
6 feet
