Guided Practice
Find the area of the following shapes.
- A parallelogram with a base of 10 m and a height of 12 m.
Answers:
- Area is 15( 6 ) = 90 un^2.
- Area is 32( 12 ) = 672 un^2.
- Area is 10( 12 ) = 120 m^2.
Practice
- Find the area of a parallelogram with height of 20 m and base of 18 m.
- Find the area of a parallelogram with height of 12 m and base of 15 m.
