To Find Area of a Rectangle when Length and Breadth are of Different Units
To find area of a rectangle when length and breadth are of different units we need to convert and write them in same units and then solve.
For Example:
1. Find the area of a rectangle whose length is 15 cm and breadth is 50 mm.
Solution:
Length (l) = 15 cm.
10 mm = 1 cm.
Therefore, 50 mm = 50/10 cm = 5 cm.
Breadth = 5 cm.
Area = l × b
= 15 × 5 sq. cm.
= 75 sq. cm.
2. Find the area of a rectangle whose length is 32 m and breadth is 200 cm.
Solution:
Length (l) = 32 m.
100 cm = 1 m.
Therefore, 200 cm = 200/100 m = 2 m.
Breadth = 2 m.
Area = l × b
= 32 × 2 sq. m.
= 64 sq. m.
3. Find the area of a rectangle whose length is 17 cm and breadth is 85 mm.
Solution:
Length (l) = 17 cm.
10 mm = 1 cm.
Therefore, 85 mm = 85/10 cm= 8.5 cm.
Breadth = 8.5 cm.
Area = l × b
= 17 × 8.5 sq. cm.
= 144.5 sq. cm.
4. Find the area of a rectangle whose length is 21 m and breadth is 500 cm.
Solution:
Length (l) = 21 m.
100 cm = 1 m.
Therefore, 500 cm = 500/100 m = 5 m.
Breadth = 5 m.
Area = l × b
= 21 × 5 sq. m.
= 105 sq. m.
5. Find the area of a rectangle whose length is 41 m and breadth is 400 cm.
Solution:
Length (l) = 41 m.
100 cm = 1 m.
Therefore, 400 cm = 400/100 m = 4 m.
Breadth = 4 m.
Area = l × b
= 41 × 4 sq. m.
= 164 sq. m.
