The length of a rectangular garden is 3 yards more than its width. The area of the garden is 40 square yards. Find the length of the garden.

length=8 , wide=5

Step-by-step explanation:

Let length=x and wide=y

convert the question into two equations

3+y=x 1

xy=40 2

so we need to substitute x into y or y into x

x=3+y ,

(3+y)y=40

y²+3y=40

y²+3y-40=0

from that use calculator or manually factorise it

(y+8)(y-5)=0

y= –8 , y=5

we need to choose positive answer so y=5

then find for x

5x=40

x=8
