Question about Area of Triangle?

Question

Settle an arguement....If the Area of a triangle is 6.75M2 and the base is 3m what is the height?

My daughter says 4.5 and I say 2.25.... Who is correct??

Answer 1

Area of a trianlge = half * base * height

A = 0.5 * b * h

6.75 m^2 = 0.5 * ( 3 ) * h ..... then h = 4.5 m

Answer 2

its 4.5 because

Area of tri = 1/2base multiplied by the hight

6.75 = 1.5 multiplied by x

divide both sides by 1.5

x equals 4.5

Hope that helps :)
