1. Find the area of a rectangle with a length of 5 cm and width of 3 cm.
Area = length x width
Area = 5 cm x 3 cm
Area = 15 square cm
2. Find the area of a right triangle with a base of 8 cm and height of 4 cm.
Area = 1/2 x base x height
Area = 1/2 x 8 cm x 4 cm
Area = 16 square cm
3. Find the area of a rectangle with a length of 12 in and width of 6 in.
Area = length x width
Area = 12 in x 6 in
Area = 72 square in
4. Find the area of a right triangle with a base of 10 ft and height of 5 ft.
Area = 1/2 x base x height
Area = 1/2 x 10 ft x 5 ft
Area = 25 square ft
5. Find the area of a rectangle with a length of 7 m and width of 4 m.
Area = length x width
Area = 7 m x 4 m
Area = 28 square m
6. Find the area of a right triangle with a base of 6 ft and height of 8 ft.
Area = 1/2 x base x height
Area = 1/2 x 6 ft x 8 ft
Area = 24 square ft
