Question

3) Half the perimeter of a rectangular garden, whose length is 4 m more than its width, is 36 m.
Find the dimensions of the garden​

Answer 1

Answer:

L=20

B=16

Step-by-step explanation:

Half the perimeter= 36

perimeter= 2(L+B)

half of the perimeter= 1/2×2×(L+B)

half the perimeter= L+B

let B be x

L= x+4

x+x+4= 36

2x+4=36

2x=36-4

2x= 32

x= 32/2

x= 16( width)

x+4= 20(length)

Answer 2

Answer:

16m and 20m

Step-by-step explanation:

Half perimeter=36m

Perimeter=72m

Let width be x metre, so length is (x+4) metre

x+x+(x+4)+(x+4)=72

4x+8=72

x=14

DIMENSIONS ARE

BREADTH=16m

LENGTH=20m
