Units change translation from cm to feets
1 cm is equivalent to 2.5 feets
triangle is a rectangular triangle suported with the bigger side
this means the height of triangle is 6cm
the base is 16 cm
the area is (base x height)/2
so then area= 16x 6/2= 48cm ^2
BUT because 1cm is equivalent to 2.5 feets then
multiply 48 x 2.5 x 2.5 = 48 x 6.25 = 300 ft^2
