Question

How do u solve this?

Answer 1

`\text{The formula of an area of a triangle:}\\\\A_\triangle=(1)/(2)bh\\\\b-base\\h-height\\----------------------\\\\\text{We have}\\\\b=41(1)/(2)ft=(41\cdot2+1)/(2)ft=(83)/(2)ft\\\\h=36ft\\\\\text{Substitute:}\\\\A_\triangle=(1)/(2)\left((83)/(2)\right)(36)=\left((83)/(\\ot4_1)\right)(36\!\!\!\!\!\!\diagup^9)=(83)(9)=747\ ft^2\\\\\\Answer:\ \boxed{A_\triangle=747\ ft^2}`
