What is the width of a rectangle with a length of 12cm and area of 192cm2

Hello!



The width of the rectangle is cm^2.

_____________________________



Formula for area is:

A = l × w

We know that we must multiply the length by the width to find the area.

Since we want to find one of the rectangle's dimensions, and not the area, we'll use the opposite operation.

What's the opposite of multiplication? Division!

-------------------------------------------------------

Divide the area of the rectangle by its length to find the width:

W = A ÷ l

W = 192 ÷ 12

W = 16

1.) 18+5 is one way i’m pretty sure there are others but i can’t think of them right now

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
