Question

1. The sum of three numbers is 90. The second numider is five me
the first and the third exceeds the first by 10. Find the numigers
OR
2. The length of a rectangle is trīce it's breadth If the Perimeter is 300 m
find its length and breadth​

Answer 1

$2) perimeter = 300m\\\\perimeter(rectangle)= 2*(l+b)$

let the breadth be x and length be 3x.

$300 = 2*(x+3x)\\\\300 = 2*4x\\\\\frac{300}{2} = 4x\\\\\frac{150}{4} = x \\\\x = 37.4m = breadth\\\\length = 4x = 4 * 37.5 = 150m$

length = 150 m

breadth = 37.5 m

hope it helps !!
