Question

5. The length and breadth of rectangular park are in the ratio 5:3 and its perimeter is 320 cm. The
length of park is :
(1) 100 cm
(ii) 90 cm
(iii) 110 cm
(iv) 125 cm​

Answer 1

Answer:

Option (i) = 100 cm

Step-by-step explanation:

Let the length be 5x

and Breadth = 3x

Perimeter of a rectangle = 2 (Length + Breadth)

320 = 2( 5x + 3x)

320 = 2 * 8x

320 = 16x

x = $\frac{320}{16}$

x = 20

So, Length = 5 * 20 = 100 cm

So, the length of the park is 100 cm.
