Question

adjacent side of a rectangle are in the ratio 5 is to 12 if the perimeter of the rectangle is 35 cm find the length of the diagonal

Answer 1

Answer:Here in the question the perimeter will be 34 cm you have to correct it.

Here is your solution

Given :-

ratio 5:12

perimeter is 34 cm

Let,

the sides be 5x and 12x.

perimeter of rectangle =2 (l+b)

=>34=2(5x+12x)

=>34=34x

=>x=1 cm

breadth =5x=5×1=5cm

length =12x=12×1=12cm

length of diagonals =5^2+12^2=13cm

hope it helps you

Step-by-step explanation:

Answer 2

Answer : 3

What they given as perimeter is wrong take 34 as perimeter

Step-by-step explanation:

Length:breadth =5:12

Perimeter =2(l+b)

34= 2(5x+12x)

34=2×17x

X=34/34=1

Length =5

Breadth = 12

Diagonal= root of 12^2+5^2

= root over 144+25

= root 169

=13
