hope it helps u
plz make me brain list
ans is 464m
Step-by-step explanation:
Length = l
Breadth = b
lb = 10092sqmeter
and l = 3b (given) then put it on area.
3b × b = 10092
b×b = 10092÷3 = 3364
b =
\sqrt{3364} = 58
3364
=58
then perimeter = 2 (l+b)
l = 3× 58 = 174
p = 174+58 = 232×2 = 464m

464 meters
Step-by-step explanation:
area of rectangle = l*b
and according to the question,
10092 = 3x * x ( taking width as x and length is 3times more of it )
10092 = 3x²
10092 ÷ 3 = x²
3364= x²
√3364 = x
x = 58
So width = 58 and length = 58*3 = 174
so its perimeter =2( l + b )
= 2( 58+174 )
= 2 * 232
= 464 meters
