Answer 1

Answer:

Step-by-step explanation:

2(2x+3x) = 80

10x = 80x

X= 8

Answer 2

The side of a rectangle are 16 cm and 24 cm.

Step-by-step explanation:

It is given that the adjacent side of a rectangle are in the ratio 2:3 and it's perimeter 80 cm long.

Let length and width of the rectangle are 2x and 3x respectively.

Perimeter of a rectangle is

$Perimeter=2(l+w)$

where, l is length and w is width.

Substitute l=2x and w=3x in the above formula.

$Perimeter=2(2x+3x)$

$Perimeter=2(5x)$

$Perimeter=10x$

Perimeter is 80 cm .

$10x=80$

$x=8$

The value of x is 8.

$Length=2x=2(8)=16$

$width=3x=3(8)=24$

Therefore, the side of a rectangle are 16 cm and 24 cm.
