Question

3. Find the dimension of rectangular garden with an area of 63 mr and perimeter of 32 m. A. 9 m and 7 m C. 16 m and 2 m B. 21 m and 3 m D. 10 m and 6 m​

Answer 1

Answer:

16 meters

Step-by-step explanation:

Let the width of the garden =x meter

Then length=(x+4) meter

Half perimeter =36 m

So perimeter of garden =(2×36)=72 meters

According to the question

⇒2(l+b)=72

⇒2(x+x+4)=72

⇒2x+2x+4=74⇒4x=64⇒x=16 meters

Hence,the width of the garden =16 meters

The length of the garden =(16+4)=20 meters
