Question

The perimeter of a rectangle is 170 cm. One of its sides is 5 cm more than the other. Find the sides of the rectangle.

Answer 1

Answer:

Here's how to find it:-

We know that the equation to find perimeter of rectangle is:-

2 (length + breadth)

Given that one side is 5cm longer than the other

So,

breadth can be taken as x

and length can be taken as x+5

Substituting this in the equation,

2 ( x+ x + 5) = 170

2 (2x + 5) = 170

2x + 5= $\frac{170}{2}$

2x + 5 = 85

2x = 85 - 5

2x = 80

x = $\frac{80}{2}$

x = 40

So, breadth is 40cm.

We took length as breadth + 5cm,

So , length will be 45 cm.

Answer 2

Answer:

80

perimeter =2(length+Breath)

=2*(80+5)

=2*85

=17.
