Two sides of a triangle are not enough to determine its shape and so it is impossible to find its area.
The area of triangle is : 12.0
About 62 Feet squared
20 ft
6 x 12/2 ie 36 sqft
4X12=48 48/2=24.
The area of triangle is : 60.0
The area of triangle is : 12.0
About 62 Feet squared
60 square feet.
It is: 0.5*12*5 = 30 square feet
20 ft
6 x 12/2 ie 36 sqft
120
A=.5bh_____27ft square=.5*12*h____27=6h_____4.5=h_____so the height is 4.5 feet
4X12=48 48/2=24.
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.
A rectangle measuring 15 feet by 12 feet has an area of 180 square feet. A triangle measuring 15 feet by 12 feet has an area of 90 square feet.
