• # question_answer 24) A table-top measures 2 m by 1m 50 cm. What is its area in square metres? TIPS Firstly, convert the measures in same unit say m using decimals. Then, Area of table-top = Length $\times$ Breadth.

Given, length of the table-top = 2 m and breadth of the table-top = 1m 50 cm = 1m + 50 cm $=1m+50\times \frac{1}{100}m$ $\left[ \because 1cm=\frac{1}{100}m \right]$ $=1m+\frac{50}{100}m=1m+0.50m=3.50m$ $\therefore$ Area of the table-top = Length$\times$Breadth = 2 m $\times$ 1.50 m= 3sqm Hence, the area of the table-top is 3 sq m.
