Question

Find the length and breadth
of a rectangle whose area is 25a^2-35a+12

Answer 1

Hello Dear!!!

Here's your answer...

(5a-3) and (5a-4) are the factors of 25a^2-35a+12

25a^2 - 35a + 12

25a^2 -15a -20a +12

5a(5a-3) - 4(5a-3)

(5a-3) (5a-4)

Length is 5a - 3

Breadth is 5a - 4

Answer 2

Given Area:

25a²-35a+12

To Find :

Length and Breadth

Solution :

Factorising 25a²-35a+12

[By mid term spilting]

25a²-20a-15a+12

5a(5a-4)-3(5a-4)

(5a-4)(5a-3)

Length = 5a-4

Breadth = 5a-3
