Question

The length of the rectangle is 2 cm more than thrice its breadth .If the Perimeter is 76 cm then find the length of the rectangle?​

Answer 1

Step-by-step explanation:

let the breadth be x cm

according to question length is ( 3 x +2 ) cm

perimeter of rectangle = 2 ( l + b) = 76 cm

2 ( 3 x +2 + x) = 76 cm

4 x +2 = 76/2

4 x +2 = 38

4 x = 38- 2

4 x = 36

x = 9

Breadth= 9 cm

Length = (3 × 9 + 2) cm = ( 27 +2 )cm

= 29 cm
