Answer 1

Step-by-step explanation:

$\huge\underline\bold\fcolorbox{black}{cyan}{Question}$Find the length of the rectangle of area 1190 sq.m and breadth 34m. Also find its perimeter.$\huge\pink{\fbox{\bf{Answer}}}$Let length be a m and breadth be b m.

Daigonal =34 m

=>a2+b2=(34)2

=>a2+b2=1156

Also,

2(a+b)=92

=>(a+b)=46

Area of rectangle =(ab) m2

Now,we know,

(a+b)2=a2+b2+2ab

=>(46)2=1156+2ab

=>ab=22116−1156

         =2960

         =480

Therefore,

Area =480 m2
