Question

the perimeter of a theatre is 160. if its length is 45 metre ,what is its breadth ?​

Answer 1

Step-by-step explanation:

Perimeter of a theatre, P=160

Length of a theatre, L=45

Breadth of a theatre,

B=(P/2)-L

=> B=(160/2)-45

=> B=80-45

=> B=35

Hence, Breadth = 35.

Answer 2

Answer:

perimeter of a. rectangle=2(l+b)

perimeter=160

l=45

b=?

160=2(45+b)

160=90+2b

160-90=2b

70=2b

70/2=b

b=35 meter
