Q. Nisha likes to make small rectangular paintings of cats. One of her paintings has an area of 33 cm2 33 \mathrm{~cm}^{2} and a width of 712 cm 7 \frac{1}{2} \mathrm{~cm} .\newlineWhat is the height of this painting?\newlinecm \mathrm{cm}
  1. Identify Formula: Identify the formula for the area of a rectangle.\newlineThe area AA of a rectangle is given by the formula A=width(w)×height(h)A = \text{width} (w) \times \text{height} (h).\newlineA=w×hA = w \times h
  2. Given Values: Given values for the area and width.\newlineThe area AA of Nisha's painting is 33cm233\,\text{cm}^2, and the width ww is 7.5cm7.5\,\text{cm} (since 712cm7\frac{1}{2}\,\text{cm} is the same as 7.5cm7.5\,\text{cm}.)
  3. Solve for Height: Solve for the height hh using the area formula.\newlineSubstitute the given values into the area formula and solve for height hh.\newline33cm2=7.5cm×h33 \, \text{cm}^2 = 7.5 \, \text{cm} \times h
  4. Divide and Isolate: Divide both sides of the equation by the width to isolate the height. \newlineh=33cm27.5cmh = \frac{33 \, \text{cm}^2}{7.5 \, \text{cm}}
  5. Perform Division: Perform the division to find the height. h=4.4cmh = 4.4\, \text{cm}
