What are the dimensions of a rectangle with an area of 45 square inches and a perimeter of 28 inches? A) 8 in. x 6 in.B) 9 in. x

grigory [225]

Length be x
Breadth be y

$\\ \rm\Rrightarrow 2x+2y=28$

$\\ \rm\Rrightarrow x+y=14$ --(1)

And

xy=45

$\\ \rm\Rrightarrow (x-y)^2=(x+y)^2-4xy$

$\\ \rm\Rrightarrow (x-y)^2=14^2-4(45)=196-180$

$\\ \rm\Rrightarrow (x-y)^2=16$

$\\ \rm\Rrightarrow x-y=4$ --(2)

Adding (1) and (2)

2x=18
x=9

And

9+y=14=>y=5
