Question

The length of a rectangle is 45m and it's perimeter is 150m. what is it's breadth?

Answer 1

Answer:

Length = 45 m

Perimeter = 150 m

Perimeter = 2 ( l+ b )

150 m = 2( 45 + b )

150 m = 90m + 2b

150m - 90 m = 2b

60 m = 2b

b = 60/ 2

b = 30 m

Step-by-step explanation:

Answer 2

The correct answer is 30 meters
Solving
Perimeter=2l+2b
150m=2*45m+2b
150m=90m+2b
60m=2b
30m=b
