Answer:
width=20m,length=23m
Step-by-step explanation:
as shown in the figure which is attached
let width of pool =x
⇒ length of pool=x+3
width of walk =2
⇒width of outer boundary of walk=x+4 (2 on each side of pool)
length of outer boundary of walk=x+3+4=x+7
area of pool =x×(x+3)
area of walk+pool=(x+4)×(x+7)
given
total area of the pool and walk is 188 square meters more than the area of the pool
⇒(x+4)×(x+7)=188+x×(x+3)
⇒8x=160
x=20m
dimensions of pool
widh=20m
length=20+3=23m
