Question

If perimeter of a school play is 144cm . If length of the school play ground is twice its breadth, then find the length of the playground.​

Answer 1

Step-by-step explanation:

let the length be 2x cm and the breadth be x cm

perimeter = 2(l+b)

144 cm= 2(2x+x)

144 cm =2(3x)

144 cm = 6x

x = 144/6

x = 24 cm

length =2x = 2×24 = 48cm
