Question

The diagonal of a rectangle
is 1cm more than it's length
and the breadth of a rectangle
is 7cm less than it's length.
Find the dimensions of the
rectangle.

Please help me...!​

Answer 1

Step-by-step explanation:

diagonal = 1 + L

length = L

width = L - 7

formula = 2L + 2w

= 2(L)+2(L-7)

= 2L+2L-14

= 4L - 14

= 2(2L-7). here L = 12 or 4

= 2(2(12)-7)

= 2(24 -7 )

= 2(17) = 34 or

=2(8-7) = 2(1) = 2 ... plz mark it has brainest

if you ask how you took the value of L ? then see the attachment !!

Answer 2

Answer:

length:-12, breadth:-5, diagonal:-13

Step-by-step explanation:

let length=X cm , breadth=x-7, diagonal=X+1 ,

let diagonal=hypotheses

using Pythagoras theorem:- (hypotheses )2=(side)2+(side)2

(AC)2=(AB)2+(BC)2

(X+1)2=(x-7)2+(X)2

X2+1.2+2 x.1 =X2 +7.7-2.7x+x2

X2+12x+14x-49=0

(x-12).(-x+14)=0

X=12 length

breadth=x-7=5

diagonal=X+1=13
