Question

find the breadth of the rectangle given below if its perimeter is 72 metre​

Answer 1

Answer:

perimeter of a rect is 72

2a+ 2 b = 72

(a+ b) 2= 72

a + b is 36

Step-by-step explanation:

b= 36- a

a= 36-b

Answer 2

Answer:

B = 36 - L

Step-by-step explanation:

perimeter of rectangle = 2(L + B)

72 = 2( L+B)

72 = 2L + 2B

2B = 72 - 2L

B = 72 - 2L / 2

B = 2(36 - L) / 2

B = 36 - L
