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

• math -

area=L*B

• math -

change 50mm to 5 cm

• math -

First change cm to mm

350 cm = 3500 mm

Area = L x W

3500mm = L(50mm)

Divide to solve for L

• math -

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