Question

the perimeter of a square is 32cm .A rectangle with the same perimeter has its length three times is width find the sides of the rectangle.
​

Answer 1

Answer:

length = 24 cm and width = 8 cm

Step-by-step explanation:

let sides be x and y

perimeter of rectangle = 2( x+y )

given perimeter is 32 cm

Therefore, 2( x+y ) = 32 cm

Then x + y = 16cm

ATQ , X = 3Y

=> y + 3y = 16 cm

=> 4y = 16 cm

=> y = 4 cm

then , x= 3y = 3 * 4 = 12 cm

Answer 2

Answer:

the length =x

the width=x

the length is 3 times the width

so

the length =3x

the width =x

and the equation is x+3x=32

4x=32

x=32÷4

x=8

so the length =3x=3×8

=24

and the width =x=8

a rectangle has two equal sides

so length = 24÷2

=12

and has two width =8÷2

=4

so the sides are 12,12,4,4
