If the surface area for the coloured tile is 286cm², find the
value of x.

pls hlp（-""-；)

x=8.72389

Step-by-step explanation:

first you make every number 10 times larger

25*10, 48*10, etc etc

you find that you have 12x

the difference between the two surfaces is

120000 (250*480)- 28600= 91400

12x²+20=91400

12x²=91400-20

12x²= 91380

x²=91380/ 12

x²= 7615

x= √7615

x= 87.2389

and since we had made everything 10 times bigger

x=8.72389

i hope you understand i am not good with the words but i think you can understand what i did.

it is 2 moths
