Perimeter = 20+20+15+15 = 70 feet
100
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

To balance the seesaw, your partner should weigh 144 pounds. This is because the weight of each person multiplied by their distance from the fulcrum should be equal. So, 120 pounds Γ 15ft = Partner's weight Γ 20ft, which amounts to 144 pounds.
