Question

find the value of x so the rectangles have so the rectangles have the same area. There are two rectangles. One rectangle has x and 12. The other rectangle has 16 and x-2. I don't know If this makes any sense but I really need help

Answer 1

x*12=16(x-2)
12x=16x-32
4x=32
x=8

Answer 2

are of rect = length * breadth

since areas of both rect is same
x * 12 = 16*(x-2)

Answer 3

12x = 16x - 32
32 = 16x - 12x
32 = 4x
32/4 = x
8 = x

Answer 4

thanks so much :D
