Answer:
24 and 21 are the two numbers
Step-by-step explanation:
let n represent the unknown number
let n-3 represent the second unknown number
n+n-3 = 45
2n-3=45
2n=45+3
2n=48
n=48/2
n=24
n-3=21
CHECK: 24+21=45
.˙. the first number is 24 and the second number with a difference of 3 is 21
Perimeter=2(l+w)
36=2(l+w)
(l+w)=18
l=18-w
area of a rectangle=w*l
put value of l here
Area=w*(18-w)
Area=18w-w^2
