Question

what will be the length of a rectangular park which is 70 m wide and has a perimeter 520m
​

Answer 1

Answer:

b=70 m

perimeter =520m

perimeter of rectangle =2(l+b)

520 =2(l+70)

520/2-70=l

260-70=l

190=l

Answer 2

Answer:

Step-by-step explanation:

Perimeter of rectangle=2×(l+b)

Width=70m

Perimeter=520m

Let the length be 'x'

520=2×(x+70)

520÷2=x+70

260=x+ 70

260-70=l

190=l

Length of the rectangular park=190m
