1.	ruchi takes 15 rounds of rectangular park whose legnth is twice its breath. if total distance covered by ruchi is 900 m , find the length and breadth of of park
Answer» Answer: Distance COVERED by Ruchi in 1 round = 900m ÷ 15 = 60m Breadth of park = X Length of park = 2X Perimeter of park = 60m 2 (2x + x) = 60 2 (3x) = 60 6X = 60 x = 60 ÷ 6 x = 10 Hence, breadth = x = 10m Length = 2x = 2 × 10 = 20m

ruchi takes 15 rounds of rectangular park whose legnth is twice its breath. if total distance covered by ruchi is 900 m , find the length and breadth of of park

Answer»

Answer:

Distance COVERED by Ruchi in 1 round = 900m ÷ 15 = 60m

Breadth of park = X

Length of park = 2X

Perimeter of park = 60m

2 (2x + x) = 60

2 (3x) = 60

6X = 60

x = 60 ÷ 6

x = 10

Hence, breadth = x

= 10m

Length = 2x

= 2 × 10

= 20m
