Question

the width of a rectangle is 20cm. Its length is 10cm more than the twice its width. find the perimeter

Answer 1

Answer:

140cm

Step-by-step explanation:

Width (breadth) = 20cm

length = (20 × 2) + 10 = 50cm

So perimeter of a rectangle = 2 × (l + b)

P = 2 × (20+50) = 2 × 70 = 140cm

Hope this helps :)

Answer 2

Answer:

perimeter of rectangle Is 140cm

Step-by-step explanation:

width of a rectangle (w)=20cm

length (l) =10cm more tha n twice it's width

the width is 20cm

it's twice will be 40cm

if the length is 10 more

then the length will be 50

therfore (l) = 50

perimeter =2(l+w)

= 2(50+20)

= 2(70)

=140 cm

hope this helps you
