Question

The length of a rectangle is 6cm more then three times its breadth . The perimeter is 132cm. Its length is​

Answer 1

Answer:

15cm

Step-by-step explanation:

P= 2(L +B)

2(6+3X + X)=132

2(6 +4X)=132

6+ 4X=66

4X=60

X=15

therefore length=15

Answer 2

Step-by-step explanation:

1. let breadth=x
2. length=3×x+ycm.

• perimeter=132cm.

so, A.T.Q=permimeter=length

132cm.=3x+6cm

132-6cm.=3x

126cm.=3x

126/3=x

42cm=x

Answer=length =42cm
