Question

find the breadth of the rectangle whose length is three times its width and it's width and it's perimeter is 568 meters. also find its area of rectangle.

Answer 1

let, width be x
according to question, length = 3x
Given:- perimeter = 568 m
To find :- Area = L * B
perimeter = 2(L+B)= 2(3x+x)=568
from here x = 71m
so, breadth = x = 71 m
and, length = 3x = 213m
so, Area= 213 * 71 =
$213 \times 71 = 15123m {}^{2}$
