Step-by-step explanation:
I have answered ur question
The rectangle is 7 x 4 so the area is 28 sq cm
The triangle has a base of 4 and a height of 3.
The formula is A = 1/2 * b*h
You have 2 triangles so:
2(1/2)*4*3= 12 sq cm
Add together:
28 + 12= 40 sq cm
THE ANSWER IS 70 !!
When you add up all the sides to get 290 and the total amount of the angles is 360 so you subtract 290-360 and you get 70
