Question

the area of plastic sheet is 300 sq cm and its length is 30 cm. what is the breadth of the plastic sheet ?

Answer 1

Let breadth be x
Area of the sheet = l X b
300 = 30 × X
or, 30 x X = 300
or, X = 300 ÷ 30
or, X = 10.
Therefore, the breadth is 10 cm

Answer 2

area = length × breadth
300 sq cm = 30 × b
b = 300/30
b= 10 cm
