<span>I think you meant this: (3m/m-6)*(5m^3-30m^2/5m^2)
If that's the case, the simplified form:
=3m</span>
The area of the triangle is 14.625.... in order to find the area of a triangle just use this formula b×h÷2
remember that when total value is used a negative number is turned positive so it equals to 282 feet
192 in2
The formula for surface area is 2(lw + wh + hl) = 2(2*8 + 12*8 + 12*2) = 2(16+56+24) = 2(96) = 192
