Question

The length of a rectangle is 3 cm more than twice the breadth. If it’s perimeter is 72 cm, find the length and breadth

Answer 1

Answer:

Length = 25

Breath = 11

Step-by-step explanation:

Answer 2

Answer:

L= 19.5cm B=16.5cm

Step-by-step explanation:

let the breadth of the rectangle be x cm

length of rect= (x+3)cm

breadth of rect= x

perimeter= (l+b)*2= [(x+3) + x] *2= 72 cm

[(x+3) + x] *2= 72

(x+3) + x= 72/2

(x+3) + x= 36

x+3+x=36

2x+3=36

2x=36-3

2x=33

x=33/2

x=16.5

breadth=16.5 cm

length =x+3 cm= 19.5cm

CHECK

p= (l+b)*2 = (19.5+16.5)*2 = 36*2= 72
