Question

The length and the width of a rectangular plot are 18 units and 6 units respectively. Using area model, find the area of the plot. Which of the following gives the values of P and area of the plot?

• A. 600 sq units, 48 sq units
• B. 60 sq units, 108 sq units
• C. 10 sq units, 48 sq units
• D. 60 sq units, 48 sq units

Answer 1

The correct option is B 60 sq units, 108 sq units

From the given area model, 18 is decomposed into 10 + 8.

Area = 6 $\times$ (10 + 8)

= 6 $\times$ 10 + 6 $\times$ 8

= 60 + 48

= 108 sq units

Hence, value of P = 60 sq units

Area of the plot = 108 sq units
