❥A᭄ɴsᴡᴇʀ࿐ given, area=a²–b² breadth=(a–b) To find :– length of rectangle let length is l units area of rectangle =length×breadth a²–b²={a–b}×l ––––––––––(1) using identity a²–b²=(a+b) (a–b) substituting value of a²–b² in equation (1) (a+b) (a–b)= (a–b)×l l=(a+b) unit length of rectangle is (a+b) unit.

Let l , w be the length , width/breadth of the rectangle respectively.
then,
ar(rect) = l*w = a^2 – b^2 ———(1)
now , w = (a-b) ——–(2)
substituting the value of 2 in 1 , we get

L * ( a-b) = (a^2-b^2)
l = (a^2 – b^2) / (a-b) [using identity x^2 – y^2 = (x-y)(x+y)]
l = (a-b) (a+b) / (a-b)
l = a+b

given,
area of rectangle =length×breadth
a²–b²={a–b}×l ––––––––––(1)
length of rectangle is (a+b) unit.
