Question

The length of a rectangular shaped park exceeds its breadth by 15 metres. If the
perimeter of the park is 170 meters, then length of the park is
a) 50m
b) 49m
c) 20m
d) 52m​

Answer 1

Step-by-step explanation:

$let \: breadth \: = b$

$let \: length \: =b + 15$

$2(b + b + 15) = 170$

$2b + 15 = 170 \div 2$

$2b = 85 - 15$

$2b = 70$

$b = 35$

$l = 35 + 15 = 50$
