Question

Give possible expression for the length and breadth of rectangle whose
area is given by: 4
2+ 4a - 3

Answer 1

Step-by-step explanation:

Area of rectangle = 4a²+4a-3

4a²+4a-3 = l×b

4a²+6a-2a-3=l×b

2a(2a+3)-1(2a+3) = l×b

(2a-1)(2a+3)=l×b

a=1/2 or -3/2 but length or breadth can't be negative

so A = 1/2

now putting a= 1/2

4×1/4 + 4×1/2-3=l×b

0 = l×b
