Question

Find the area of a rectangular table cloth that is 2 m long and 1 m 25 cm wide.

• A. 2.50 sq m
• B. 2 sq m
• C. 200 sq m
• D. 25 sq m

Answer 1

The correct option is A 2.50 sq m

Given:
Length of the table cloth = 2 m
Width of the table cloth = 1 m 25 cm

We know:
1 m = 100 cm
or 100 cm = 1 m

$\therefore$ 1 cm = $\frac{1}{100}$ m

$\therefore$ Width of the table cloth
= 1 m 25 cm
= 1 m + $\frac{25}{100}$ m
= 1 m + 0.25 m
= 1.25 m

Area of a rectangle = Length $\times$ Width

$\therefore$ Area of the table cloth
= $2\text{m}\times 1.25\text{m}$


Thus, the area of the table cloth is 2.50 sq m.
