Question

The perimeter of a rectangle is 134 cm.if its length is 3cm more than its breadth, find the length and breadth of rectangle​

Answer 1

Answer:

b=32 cm, l=35 cm

Step-by-step explanation:

Let breadth be 'b' and length be (b+3)

Perimeter of a rectangle= 2(l+b)

134= 2 x {(b+3)+b}

134= 2 x (2b+3)

134= 4b+6

134-6=4b

128=4b

b=128/4

b=32 cm

l= (b+3)= 32+3=35 cm

Answer 2

Step-by-step explanation:

let breadth be x cm

then, length is (x+3) cm

perimeter is :

$2(lenght \: \times \: breadth) \\ = 2(x + 3 + x) \\ = 2 \times (2x + 3) \\ = 4x + 6 \\ = 134 \: cm$

$according \: to \: the \: problem \\ 134 = 4x + 6 \\ 4x = 134 - 6 \\ x = 128 \div 4 \\ x = 32$

breadth is 32 cm

length is 35 cm. (32+3)
