Question

The two sides of a square are given by the expressions 3x+13x+1 and 4x-4. Find the perimeter of the square ?

Answer 1

Perimeter of square = $4\times side$

Sides are given by $3x+1$

In square the sides of are equal

$\therefore 8x+1=4x-4$

$\Rightarrow 5=x$

hence side = $3\times 5+1=16$

$\therefore$ Perimeter = $4\times 16$

$=64$.
