Question

1. Perimeter of our school ground is 60 m. The length is 18 m. Find
the breadth of the ground.​

Answer 1

Answer:

Perimeter = 2( l + b )

60m = 2 ( 18 + b )

60/2 = 18 + b

30 = 18 + b

b = 30-18 = 12m

breadth is 12m

Answer 2

Answer:

Breadth of school ground = 12m

Step-to-step explanation:

Perimeter of school ground= 60m

Length of the school ground=18m

$\frac{P}{2}-L\\\\\\\frac{60}{2}-18\\\\30m-18m=12m$

∴breadth of school ground = 12m
