A triangular sail has a base length of 2.5 meters. The area of the sail is 3.75 square meters. How tall is the sail?

height = 3m

The area (A) of a triangle is.

##color(red)(|bar(ul(color(white)(a/a)color(black)(A=1/2bh)color(white)(a/a)|)))## where b is the base and h, the perpendicular height.

here A = 3.75 and b = 2.5 .Require to find h.

##rArr1/2xx2.5xxh=3.75rArr1.25h=3.75##

divide both sides by 1.25

##(cancel(1.25) h)/cancel(1.25)=3.75/1.25##

##rArrh=3m" is the height of the sail"##
