Question

The width of a rectangle is x cm and its length is (x + 5) cm. write data down an equation for the perimeter of the rectangle,giving your answer in the simplest form . the perimeter of the rectangle is 62cm ​

Answer 1

width = 13 cm , length = 18

Explanation:

the perimeter (P) of a rectangle is calculated as

P = 2( length + width)

given P = 62

substitute values into the formula for P

62 = 2(x + 5 + x)

62 = 2(2x + 5) ← divide both sides by 2

31 = 2x + 5 ( subtract 5 from both sides )

26 = 2x ( divide both sides by 2 )

13 = x

and x + 5 = 13 + 5 = 18

width = 13 cm and length = 18 cm
