Question

the area of a rectangle is 240sq. cm. if its lenght is 20cm, calculate its breadth.

Answer 1

We know that
Area of rectangle = Length * Breath
Here,
Length =20cm
let breath be b
Area=240
according to the problem
l*b=area
=20*b=240
=b=240/20
=b=12

Answer 2

the area of rectangle= 240sq
let the breadth be x cm.
length=20 cm (given)
formula of area=length×breadth

A/q
20×x=240
=20x = 240
= x =240÷20
= x = 12
therefore, breadth = x cm = 12 cm
