Step-by-step explanation:
You have to decompose the figure. Cut it into different sections like squares, triangles, and rectangles so you can find the area. Once you have decomposed it, multiply the sides of each section to find the separate area of each square, triangle, rectangle, etc then add up those areas.
1) 4a/5
a% of 80 = a% (80) = (a/100)(80) = 80a/100 = 4a/5
2) 17b/100 or 0.17b
17% of b = (17/100)(b) = 17b/100 [ = 0.17b ]
3) ab/100
a% of b = (a/100)(b) = ab/100
