Answer 2

Answer:

158.5 m, 51.5 m

Step-by-step explanation:

Let breadth = x m

Then length = 3x + 4 m

Perimeter = 2 ( l + b )

Given, perimeter is equal to 420 m

420 = 2(l+b)

210 = l + b

x + 3x + 4 = 210

4x + 4 = 210

4x = 206

x = 206/4 = 51.5 m

breadth = 51.5m

length = 3x + 4 = 3*51.5 + 4

= 158.5 m

LENGTH = 158.5 M

BREADTH = 51.5 M
