Question

The length length of a triangle is 12 CM morethen its breadth. if if the perimeter is 48 CM. what what are its length and breadth,pls tell it's really urgent who will tell the answer will be marked as a brainliest​

Answer 1

Answer:

let the breadth of the rectangle be a

then it's length = a + 12

Perimeter of rectangle = 48cm

=> 2 ( l + b ) = 48 => ( 2a + 12 ) = 24

=> 2a = 12 => a = 6

∴ Breadth of the rectangle = a = 6cm

Length = a + 12 = 6 + 12 = 18cm
