Area for a triangle is (1/2) bh or bh/2
So using this info, b = 1.5 m and h = x and A = 1.5 m^2
A = bh/2
1.5 = 1.5x/2
Multiply both sides by 2 to get rid of fraction ... 3 = 1.5x
Divide both sides by 1.5 ... 2 = x so x= 1.5 m
X/7 = 6/4.2
4.2x = 42
x= 10
It is a parallelogram!
Also you haven't really put any other info...
I dont even know
