area of a triangle = 0.5 * base * height.
Hence, the base of the triangle
= 2 * area / height
= 2 * 90 [in2] / 12 [m]
we know 1 [m] = 39.37 [in]
or equivalently, 1 = 39.37 [in/m]
Therefore, base
= 2 * 90 [in2] / (12 [m] * 1)
= 2 * 90 [in2] / (12 [m] * 39.37 [in/m] )
= 2 * 90 [in] / (12 * 39.37 )
= 0.381 [in]
===============
area=basexheight/2 bring two over to ninety side 90x2=180 180=12xbase 180/12=15 base=15 =============== The second author above has forgotten about the units -- the area given is in square inches and the height is in meters.
