Question

3. Find the area of the figure. All angles in the fig are right angles3 mm 9 mm 5 mm 9 mm 0272 mm

Answer 1

57 mm²

1) Since we have a polygon made of two figures we can calculate it this way:

2) Since for the vertical rectangle

S= wl Rectangle's area

S= 3 x 9 = 27 mm²

and for the "horizontal one"

S= 6 x 5

S = 30 mm²

3) Adding it all up, we have

S =30 +27 = 57 mm², and that is the answer.
