Using Pythagoras' theorem the 3rd side is 8 feet providing it is a right angle triangle.
If it's a right angle triangle then its hypotenuse is 10ft and its sides are 6ft and 8ft
Assuming the shape is a triangle, the area is 11.40 sq ft, approx.
10+8+6=24ft
The area is the product of (Length) times (Width)6ft by 10ft = (6 x 10) = 60 square feet.
6ft by 10ft = 60 square feet
The area of the rectangle is the product of the length of the sides (provided the units of length are the same). Imagine a rectangle 6ft long and 10ft wide. You could even draw it if it helps. 6 multiplied by 10 is 60, so the area of a 6ft*10ft rectangle is 60ft2 or 60 sq. ft.
10ft x 6ft = 60 sq ft = 5.57 sq metres, approx.
60 feet squared
1346 gallons
8ft x 6ft x 10ft = 480 sq. ft.
10*8*6 = 480 cubic feet
For a triangle Area = (base x height)/2 So Area = 6x3/2 = 9 square feet
