Question

the side of a rectangular field are x²+3 meter and x²-4 meter find the area and perimeter​

Answer 1

Step-by-step explanation:

the sides are x^2 + 3 and x^2 -4.

now. area of the. rectangle is

= (x^2+3 ) (x^2-4)

= x^4 - 4x^2 +3x^2 - 12

= x^4 - x^2 - 12

is ur area of the rectangle

and now perimeter is

2(x^2 +3+x^2 - 4)

.== 2 ( 2x^2 -1)

now answer is 4x^2 - 4 is ur perimeter
