Question

Draw rectangles on a square paper of which the length (a) and breadth (b) .calculate the areas and verify by the counting of actual squares
1)a=5cm b=7.5cm

Answer 1

$\begin{array}{cc}Wecandividetherectangleinsquares& \\ ofdimension0.5\times 0.5& Areaofrectangle=7.5\times 5\\ & =37.5\end{array}$
$\therefore$ We will get $\frac{7.5}{0.5}\times \frac{5}{0.5}square=150$
$\therefore area=150\times 0.5\times 0.5=37.5$
