Answer 1

Given :- A rectangle is 52 millimeters long and 20 millimeters wide. What is its area in cm² squared ? 

Answer :-

we know that,

• Area of rectangle = Length * Breadth .

so,

→ Length of rectangle = 52mm

→ Breadth of rectangle = 20 mm

then,

→ Area of rectangle = L * B = 52 * 20 = 1040 millimeters² .

now,

→ 1mm² = 0.01 cm²

→ 1040 mm² = 1040 * 0.01 = 10.4 cm² (Ans.)

Answer 2

Given : A rectangle is 52 millimeters long and 20 millimeters wide.  

To Find : area in cm² squared

Solution:

1 cm = 10 mm

1 cm²  = 100 mm²

A rectangle is 52 millimeters long and 20 millimeters wide.  

Area of rectangle = Length * width

Length  = 52 mm = 5.2 cm

Width = 20 mm =   2.0 cm

Area = 5.2 * 2.0  = 10.4  cm²

Area of rectangle = Length * width

Length  = 52 mm

Width = 20 mm  

Area = 52 * 20  = 1040   mm²

= 10.40  cm²

Area of rectangle  is 10.40  cm²
