Question

the width of a rectangle is 7.1x-3.2 feet and the length is 1.5x+6.4 feet. Find the perimeter of the rectangle

Answer 1

The perimeter of rectangle is 17.2x + 6.4 feet

Solution:

Given that width of rectangle is 7.1x - 3.2 feet

Length of rectangle = 1.5x + 6.4 feet

To find: perimeter of rectangle

The formula for perimeter of rectangle is given as:

perimeter = 2(length + width)

Substituting the given values of length and width, we get

$perimeter = 2(1.5x + 6.4 + 7.1x - 3.2)$

Combine the like terms , we get

$perimeter = 2(1.5x + 7.1x + 6.4 - 3.2)\\\\perimeter = 2(8.6x + 3.2)\\\\perimeter = 17.2x + 6.4$

Thus the perimeter of rectangle is 17.2x + 6.4 feet
