Area of any triangle: 0.5*base*height
Perimeter = 3*8 = 24 feet
Area = pi*42 = 50.265 feet to 3 d.p.
48 square ft
15 ft
Area of triangle = 1/2 (base x height) = (8 x21)/2 = 84 sq.ft.
Area of any triangle: 0.5*base*height
An 8ft x 8ft rectangle is actually a square. The area is l x w = 8ft x 8ft = 64ft2.
If it's a right angle triangle then its hypotenuse is 10ft and its sides are 6ft and 8ft
To find the volume you would first find the area of the triangle (in square feet.) The area of a triangle is 1/2 x base x height. If the triangle is equillateral (all sides the same length) and the sides are eight feet long, then the equation is (1/2) x (8ft) x (8ft) = 32 square feet. Then you take this area and multiply it by the depth. The depth is (3.5/12) because it is in inches rather than feet. So, your answer is 9 1/3 cubic feet.
If 12.42 ft has been rounded to 2 decimal places then it is a right ange triangle
It depends on the shape. A 8ft-3ft-3ft triangle is impossible, a circle needs only one measure, a square only 1, a rectangle 2. Other quadrilaterals need more than 3. So the shape is indeterminate and, therefore, it is impossible to calculate the area.
The area CANNOT be 20 ft since that is a measure of distance, not of an area. Assuming you meant 20 SQUARE feet, if the shape was a triangle, then 5 ft. if the shape was a rectangle, then 2.5 ft.
Perimeter = 3*8 = 24 feet
would think you say 6ft*8ft = 48ft^2formel:If a rectangle has length l and width wit has area A = lw,
Multiply width by length to get the area. The answer would be 70.7 square feet.
Area = pi*42 = 50.265 feet to 3 d.p.
