Question

Half the perimeter of a rectangular garden whose lenth is 4m more than its width is 36m find the dimensions bof the garden

Answer 1

Answer:

20m ,16m

Explanation:

1/2perimeter=36m

• perimeter=72m
• breadth=b
• length=b+4

perimeter =2(l+b)

72=2(b+4+b)

36=2b +4

2b=32

b=16

l=b+4=20

hope my answer helps

please mark the question as brainliest

Answer 2

answer: l=20 & b= 16

Step-by-step explanation:

1) peri of rect=2(l +b)

2) peri. = 2(l+b)/2

3) peri= l+b

4) peri= 36m

5) 36m =l+b

now, let the width be x

then,length will be x +4

so,

6) 36m=(x+4)+(x)

7)36m=2x+4

8) 36-4=2x

9) 32=2x

10) x= 32/2

therefore, x=16

& x+4= 20
