Hey! So you have a net of the figure. It's broken into several 2D shapes. What you an do it find the area of each shape and add it together. Triangles: A = (b*h)/2 A= (5 * 3) / 2 A = 15/2 same thing for the second one 15/2 * 2 = 15 Don't forget, there are 2 triangles so it's really 15 for both
Rectangles: A=b*h A= 7*5 A=35
A=7*5 A=35
A=3*7 A=21
35+35+21=91
Now add the sum of the area of the triangles and the sum of the area of the rectangles
