If the area of a triangle is 36 5/6 feet and the base of the triangle is 6 1/2 feet, what is the height?
If the area of a triangle is 36 5/6 feet and the base of the triangle is 6 1/2 feet, what is the height?
A = 36 5/6 ft2, base (b) = 6 1/2 height (h) = ?
$${\mathtt{h}} = {\frac{{\mathtt{2}}{\mathtt{\,\times\,}}\left({\mathtt{36}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{5}}}{{\mathtt{6}}}}\right)}{\left({\mathtt{6}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right)}}$$
$${\mathtt{h}} = {\frac{\left({\mathtt{73}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}{\left({\mathtt{6}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right)}}$$
$${\mathtt{h}} = {\frac{\left({\frac{{\mathtt{442}}}{{\mathtt{6}}}}\right)}{\left({\frac{{\mathtt{39}}}{{\mathtt{6}}}}\right)}}$$
$${\mathtt{h}} = {\frac{{\mathtt{2\,652}}}{{\mathtt{234}}}} \Rightarrow {\mathtt{h}} = {\mathtt{11.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$
A = (1/2)bh ... so.....
36 + 5/6 = (1/2)(6 + 1/2) h and 36 + 5/6 = 221/6 and 6 + 1/2 = 13/2 ...so.....
221/6 = (1/2)(13/2) h
221/6 = (13/4) h multiply both sides by 4/13
(221/6)(4/13) = h
(221/13)(4/6) = h
(221/13)(2/3) = 442 / 39 = 34/3 ft = h = (11 + 1/3) ft
