Question

if ab is 5cm longer than bc, calculate the perimeter of the rectangle

Answer 1

Answer:

4x + 10 cm

Step-by-step explanation:

Let side bc be = x cm

So, side ab is = x + 5 cm

∴ Perimeter of the rectangle = 2 (l+b)

                                                = 2 ( x + x+5) cm

                                                = 2 (2x + 5) cm

                                                = 4x + 10 cm (Ans)
