I am assuming that the height is also in feet. Area of a triangle = 1/2bh = 1/2(8.56ft)(3.9ft) =16.7ft2
The formula for area of a triangle is A= 1/2bh or one-half base times height. Plug the numbers you do have into the equation: 84= 1/2(12)h so 84=6h solve for h
1/2bh which means 1/2 times the length of the base of the triangle times the height of the triangle. (1/2 x base x height)
1/2bh b=base h=height To find the are of a triangle,you have to multiply the base times height and divide the answer by 2. To find the area of a triangle you need to multiply all the sides of the triangle and then divide by 2.
a=1/2bh b=h=6 a=.5*6*6 a=18
a=1/2bh; plug in what you knwo for the area and the height and then solve
There are many formulas to find the area of a triangle although the most common is;A=1/2bh, where b=base and h=height
ANS- 1/2BH[1/228]
1/2bh trick-1/228=8cm2
Multiply 1/2 times the base times the height. A-1/2bh
1/2bh b=base h=height
Area = 1/2bh Area = 1/2(4 in)(4 in) = 8 in2 =====
the formula 1/2bh so you take the base times the height and divide it by two
A = 1/2bh 1/2 * 5 * 7 = 17.5m2
The formula is A=1/2bh b=base of triangle h=height of triangle A=area 1/2=divide base times height by 2
