Mts
A) 7
B)
8
C)
9
D) 10​

Answer 1

Answer:

option (c) 9 m

Step-by-step explanation:

If the length of rectangle is 15 m and it's  perimeter is 48 m then breadth of rectangle is

______________________________

length = 15 m

breadth = b m

perimeter = 48 m

⇒ Perimeter of rectangle = 2[length + breadth]

                                 48 = 2[15  + b]

                                 48 = 30 + 2b

                         48 - 30 = 2b

                                 18 = 2b

                                   b = 18/2

                                   b = 9 m

Breadth of the rectangle = 9 m

Answer 2

Given:

Length of rectangle=15m

Breadth of rectangle=x

Perimeter of Rectangle=48m

To find:

Breadth of rectangle=?

Formulae used= Perimeter of rectangle=2(l+b)

Solution:

Substituting values ~

2(15+x)=48

30+2x=48

2x = 48-30

2x=18

x=9 m

Therefore we can conclude that breadth of rectangle is 9 m
