Solution

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

Let Breadth = 3x and Length = 5x

5x = 25 $\Rightarrow$ x = $\frac{25}{5}$ = 5

Breadth = 3x = 15 cm

$∴$ Area = Length $\times$ Breadth = 25 $\times$ 15 = 375 $c m^{2}$

The correct option is C 375 cm2 Let Breadth = 3x and Length = 5x 5x = 25 ⇒ x = 255 = 5 Breadth = 3x = 15 cm ∴ Area = Length × Breadth = 25 × 15 = 375 cm2

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

Let Breadth = 3x and Length = 5x

5x = 25 $\Rightarrow$ x = $\frac{25}{5}$ = 5

Breadth = 3x = 15 cm

$∴$ Area = Length $\times$ Breadth = 25 $\times$ 15 = 375 $c m^{2}$
