Answer:
Width = 125 m
Length = 375 m.
Step-by-step explanation:
If the width = w then length l = 3w.
Perimeter = 2(w + l)
= 2(w + 3w)
2(w + 3w) = 1000
2 * 4w = 1000
w = 1000/8 = 125m
l = 3*125 = 375.
Step-by-step explanation:
width = x
length= 3x
perimeter of triangle =2( l + b)
1000 = 2( 3x + x )
1000÷ 2 = 4x
500=4x
x= 500÷ 4 = 125
width = 125
length = 125×3= 375
recheck by filling value
width= x = 125
length = 3x =375
perimeter = 2( l+ b)
= 2(375 + 125)
= 2× 500 = 1000
hence proved
hope it helps : )
