Question

a width of a rectangle is 15 cm what is the perimeter of the rectangle if the length is the 3 time the width?​

Answer 1

Answer:

120 cm

Step-by-step explanation:

width of a rectangle is 15 cm

length is the 3 time the width

let the width be x

hence, length is 3x

so,x=15 ,3x=15×3 = 45cm

length =45 cm

width=15 cm

perimeter =2(l + b)

2(45+15)

2 ×60

=120 cm

Answer 2

Answer:

120 cm

Step-by-step explanation:

Breadth of the rectangle = 15 cm

Length of the rectangle = (3 × breadth) cm

= (3 × 15) cm

= 45 cm

Perimeter of the rectangle = 2 ( Length + Breadth) cm

= 2 ( 15 + 45 ) cm

= (2 × 60) cm

= 120 cm

THUS,THE PERIMETER IS 120 CM AND LENGTH IS 45 CM.
