Calculate the lenght of a rectangle with area 350cm and breadth 50mm.

First change cm to mm

350 cm = 3500 mm

Area = L x W

3500mm = L(50mm)

Divide to solve for L

Jane: the 350cm should be 350 cm^2, so in square mm, it would be 35000mm^2

50m2

To calculate the length of a rectangle when only the area and breadth are given, we need to convert the units of measurement to the same system. In this case, the area is given in cm² and the breadth is given in mm.

First, let's convert the breadth from mm to cm:
1 cm = 10 mm

So, 50 mm = 50 mm / 10 mm/cm = 5 cm.

Now we have the area as 350 cm² and the breadth as 5 cm.

The formula to find the length of a rectangle is:
Length = Area / Breadth

Substituting the given values:
Length = 350 cm² / 5 cm = 70 cm.

Therefore, the length of the rectangle is 70 cm.

area=L*B

Length=area/breadth

change 50mm to 5 cm
