The length of the rectangle is 1 m 40 cm, and the width is 7 dm. Calculate the area of the rectangle.

Before starting the solution, recall the formula for finding the area of a rectangle:

S = a × b, where a is the width, b is the length of the rectangle.

Solution:

Let’s bring all the data to one unit of measurement:

1 m 40 cm = 1.4 m;

7 dm = 0.7 m.

Find the area of the rectangle:

1.4 × 0.7 = 0.98 (sq. M) – the area of the rectangle.

Answer: the area of the rectangle is 0.98 sq.
