Question

the length of a rectangle is 3 more than red and the perimeter is 22 cm find the breadth and length​

Answer 1

Answer:

Length = 7 cm

Breadth = 4 cm

Step-by-step explanation:

Let the breadth be x cm.

Then the length equals (3+x) cm.

P= 2(l+b)

A/Q  

2(l+b) = 22

=> 2(3+x+x) = 22

=> 6+2x+2x = 22

=> 2x+2x = 22-6

=> 4x = 16

=> x = $\frac{16}{4}$

=> x = 4

∴ Breadth= x cm = 4 cm

  Length= (3+x) cm = (3+4) cm = 7 cm

Verification

2(4+7) = 22

=> 8+14+22

=> 22 = 22

∴ Hence verified, length= 7 cm and breadth = 4 cm.
