Question

the length of a rectangle is 3cm longer than the breadth. the perimeter of rectangle is 38cm . determine the length and breadth of the rectangle let the breadth be x cm. the length is (x+3) cm .perimeter =2L +2b. L is length and b is breadth​

Answer 1

Answer:

l=11

b=8

Step-by-step explanation:

Let l=x+3

b=x

Perimeter=38

i.e 2l+2b=38

2(l+b)=38

2(x+3+x)=38

2(2x+3)=38

4x+6=38

4x=38-6

x=32/4

x=8
