Question

The area of a rectangular field is (5x2 – 3x - 2) square units. Find the perimeter of the field.​

Answer 1

Answer:

Step-by-step explanation:

Factorizing 5x^2-3x-2 we get

5x^2-5x+2x-2

5x(x-1)+2(x-1)

(5x+2)(x-1)

so these are the sides of the rectangle, then to find perimeter we get

2(5x+2+x-1)

=2(6x+1)

=12x+2

Answer 2

Answer:

20

Step-by-step explanation:

here area is 16

10--6=10+6

if area 16 (l*b)

then perimeter 2(l+b)

as it is rectangle

l and b should be different so cannot take4 and 4

so l and b will be 2 and 8

so the perimeter 2(2+8)=20
