Question

The area of a rectangle is 1936sq.m .If the length of the rectangle is 4times its breadth ,find the the dimensions of the rectangle

Answer 1

let breadth(b)=x
then length(l)=4x
area=l*b=>4x*x=>4x^2=1936m^2
=>x^2=(1936m^2)/4=484m^2
=>x=(✔484m^2)= 22m

.: b=x=22m
l=4x=(22*4)m=88m

.: b=22m }ans.
l=88m }ans.
