Ans is 3/4h

How to solve?

Use the relation area of the whole = Area of one rectangular space x 4 (due to the phrase “spaces of equal area”)

or if you wanna choose number then let h = 24 and w = 12

24 \times 12= 4\times(\text{height}\times\frac{w}{3})

288 = 4\times\text{height}\times4

\frac{288}{16}=\text{height}

18= height

Plug 24 into answer and see which choice returns 18

Why are we doing w/3 and not w/4 ?
