Answer:
40.32 cm square
Step-by-step explanation:
1) 4.8 divided 4= 1.2
You do this step as you know that they are similar rectangles.
2) Now you know their factor I guess you could say so you do 7 times 1.2= 8.4
3) Area of larger rectangle= 4.8 times 8.4= 40.32 cm square
13. Simple problem when you divide a fraction by another you multiply by its inverse not by the same.
So 3x-12/x^2-9x+20 divided by 9x+54/x^2+x-30
Should be: 3x-12/x^2-9x+20 * x^2+x-30/9x+54
Now you can simplify it.
3(x-4)/(x-4)(x-5) * (x+6)(x-5)/9(x+6)
Or 3/(x-5) * (x-5)/9
Or 3/1 * 1/9
Or 3/9 = 1/3
