Question

The length of a rectangle is 5 m less than the breadth. The perimeter of the rectangle is 176 cm. Find the length and breadth of the rectangle​

Answer 1

Answer:

Let the Breadth of rectangle be x

Length of rectangle = x-5

Perimeter of rectangle = 2(l+b)

→ 176 = 2(x-5 + x )

→ 176 = 2x -10+2x

→ 176 = 2x +2x -10

→ 176+10 =4x

→ 186 = 4x

→ x = 186/4 = 46.5

So, Length of rectangle = x-5 = 46.5-5 = 41.5cm.

Breadth of rectangle = x = 46.5

Answer 2

Answer:

Breadth= 46.5

Length= 41.5

Step-by-step explanation:

Let the breadth be x

Length = x-5

perimeter=2(l+b)

176 = 2(x-5+x)

176/2=  x -5 + x

88 = x-5+x

2x = 88+5

2x = 93

x = 93/2 = 46.5

Breadth = x = 46.5

Length = x-5=46.5-5 = 41.5
