Question

the sides of a rectangle are X and X + 2 cm and its area is 48 CM square find the perimeter of the rectangle​

Answer 1

Answer:28cm

Step-by-step explanation:

X and X+2 are two sides

Area of rectangle is l*b

X*X+2=48

X^2+2x=48

X^2+2x-48

X^2+8x-6x-48

X(x+8)-6(x+8)

(X-6)(X+8)

X=6,X=-8.....side the side can't be negative we have to use 8

Perimeter of rectangle 2(l+b)

X=6

X+2=6+2=8....substitute in the values of l and b

2(6+8)=28
