Question

the perimeter of a rectangular cardboard is 180 cm the length of the cardboard is 52 cm find its breadth​

Answer 1

Answer:

38 cm

Step-by-step explanation:

L of the rectangular carboard=52 cm

B ---------------------------------------=B

P----------------------------------------=180cm

                                Perimeter=2(L+B)

                                     180 cm=2(52+B) cm

                                      180cm/2=52cm +B

                                       90cm= 52cm+B

                                (90-52)cm=B

                                     38cm=B

Thus, Breadth =38 cm.

Answer 2

Answer:

The breadth of the rectangular cardboard is 38cm.

Step-by-step explanation:

P= 2(b+l)

180=2(b+52)

180=2b+104

2b=180-104

2b=76

b=$\frac{76}{2}$

b=38
