Answer: do pi times 10
Step-by-step explanation:
Answer:
length = 14 metres, width = 12 metres
Step-by-step explanation:
let x be length
length = x
width = x-2
perimeter of parallelogram = 52
length + length + width + width = 52
x+x+x-2+x-2=52
4x-4=52
4x=56
x=14
length = 14 metres
width = 14 - 2 = 12 metres
