1 answer:
Answer:
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
