Question

the perimeter of the rectangle is 90cm the length is 27cm what is the breath of the rectangle​

Answer 1

Answer:

36cm

Step-by-step explanation:

Perimeter of the rectangle= 90cm

Length=27cm

Breadth=perimeter - (2× l)

=90-2×27

=90-54cm

=36cm

Answer 2

Answer:

13

Step-by-step explanation:

Given, Perimeter of rectangle = 90cm

Length of rectangle = 27cm

Let breadth be x.

Then,perimeter of triangle =2(l+b)

=2(27+x)

=54+2x (By multiplying 54 and x with 2)

But the perimeter of rectangle = 90cm

Therefore, 90cm=54+2x

2x=90cm - 54cm

x = 26/2

x = 13
