Question

the area of a rectangular carpet is 120 metre square and its perimeter is 46 metre find the length of its diagonal
$x = y$
​

Answer 1

Step-by-step explanation:

answer attached in the picture above

Answer 2

Answer:

let length be l and breadth be b

area of rectangle =l×b=120m²

perimeter of rectangle =46m

2(l+b)=46m

l+b=23

diagonal²=l²+b²

diagonal =root(l²+b²)

=root((l+b)²-2lb)

=root((23)²-2×120)

=root(529-240)=root289=17cm
