In the following right triangle, if the sides and become twice longer, what will be the ratio of the perimeter of the triangle to its area?

1:2

Step-by-step explanation:

Initially, the base and height of a right angle triangle is 12 and 5.

The hypotenuse can be calculated using Pythagoras theorem such that,

When sides are doubled,

Base = 24

Height = 10

Hypotenuse = 26

Perimeter of the triangle = 24+10+26 = 60

The area of riangle,

Required ration,

the answer is c.

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
