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 ?
