Part 1
Which figure below shows the triangle composed into a​ parallelogram?
A.
18 m
21 m
6 m
B.
18 m
6 m
21 m
C.
18 m
6 m
21 m

Answer 1

Area = 1/2 · base · height.
Take the base = 21 m and the height = 6 m, so area = 1/2 · 21 · 6 = 63 m².

The correct figure is the one that uses 21 m as the base and 6 m as the altitude (the option that places 21 along the base and 6 as the perpendicular height).
