To find the area the easyiest divide it into 2 shapes that we know the area formula for: a triangle and a rectangle
the rectangle is 5 units by 7 units
A=l*w
A=5*7
A=35
the triangle is 4 units at the base and 5 units in height
A=bh/2
A=(4)(5)/2
A=20/2
A=10
To get the total area add the 2 areas together
35+10=45
