Question

the area of a rectangle is 8 x square- 45 y square + 18 xy and one of its sides is 4x + 15 y find the length of adjacent side

Answer 1

We know that,
area of a rectangle = length×breath
area=8 x square -45 y square +18 xy
length=2 x+15 y

8 x square -45 y square + 18 xy = (4x + 15 y) × breath

breath= 8 x square - 45 y square + 18 xy / (4 x +15 y)
breath = 2 x - 3 y
