Question

A rectangle has a length of

7x and a width of x. Write
and simplify an expression
for the perimeter of the
rectangle.​

Answer 1

Perimeter of the rectangle=16 x

Explanation:

Step 1: Determine the dimensions of the rectangle

Width=x

Length=7 x

But;

Step 2: Determine the perimeter of the rectangle

P=2(L+W)

where;

P=perimeter

L=length

W=width

In our case;

P=unknown

W=x

L=7 x

replacing;

2(x+7 x)=2 x+14 x

16 x

Perimeter of the rectangle=16 x
