Answer 1

Answer:

Answer:

\boldsymbol xx = 5 units

Explanation:

Given,

In a rectangle the length is (\boldsymbol x + 5)(x+5) units and it's breadth is (\boldsymbol x + 1)(x+1) units

Find the value of \boldsymbol xx if the perimeter is 32 units.

We know that,

Perimeter of a rectangle = 2(l + b)2(l+b)

Where,

ll denotes the length

bb is the breadth of the rectangle.

\therefore \boldsymbol{ 32 = 2[(x + 5) + (x + 1) ]}∴32=2[(x+5)+(x+1)]

Solving for \boldsymbol xx

\implies 32 = 2[(x + 5) + (x + 1) ]⟹32=2[(x+5)+(x+1)]

\implies \dfrac{32}{2} = [x + 5 + x + 1]⟹

2

32

=[x+5+x+1]
