If bianca is trying to find the area of this rectangle. she already measured one side 10cm. witch other length(s) could she measure to use in her area calculation? explain your reasoning

I wish I could say it to you but I don't know how to plan it

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
