Question

The length and the breadth of a rectangular flag is in the ratio 5 : 3. If the length of the flag is 25 cm, find the area of the flag.

• A. 355 $c{m}^2$
• B. 375 $c{m}^2$
• C. 365 $c{m}^2$
• D. 405 $c{m}^2$

Answer 1

The correct option is B 375 $c{m}^2$

The length and the breadth of a rectangular flag is in the ratio 5 : 3.

Given, length of the flag is 25 cm.

We can see 5 units represents 25 cm,
then 1 unit will represent 5 cm.

Hence, breadth of a rectangular flag
= $3\times 5$ = 15 cm

$\therefore$ Area = length $\times$ breadth = 25 $\times$ 15 = 375 $c{m}^2$
