Question

The perimeter of a rectangle is 180cm and its breadth is 34cm.the leanght of the rectangle?

Answer 1

Answer:

Perimeter of a rectangle is equal to sum of all the sides of that fig.

given - perimeter= 180cm , breadth= 34 cm

then,

2l + 2b = 180 cm ..........(l means length and b means breadth)

2l + 2× 34 = 180

2l + 68 = 180

2l = 180 – 68

2l = 112

l = 112

2

length = 56cm

Hope this will help!!!! you.

Answer 2

Answer:

L = 56cm

Step-by-step explanation:

Given,

Perimeter = 180cm

Length=?

Breadth = 34

Perimeter of rectangle = 2(l+b)

Therefore, 180 = 2(l+34)

180 = 2l + 68

180 - 68 = 2l

112 = 2l

112/2 = l

56 = l

I. e, length = 56
