Question

the area of square whose side in (x+1) metre is --------sq.meter.​

Answer 1

Step-by-step explanation:

Length of each side of square = (x+1) metre

Area of square = (side)^2 sq. unit

Area of square = (x+1)^2 sq. metre

Using Identity -

(a+b)^2 = (a)^2 + (b)^2 + 2ab

Put, a=x. b=1

(x)^2 + (1)^2 + 2(x)(1)

x^2 + 1 + 2x
