Question

the sides of the rectangle are in the ratio 2 is to 1 the perimeter is 30 cm calculate the measure of all the sites​

Answer 1

hey the answer is ....

perimeter = 2 ( l + b )

let the lengths be x

= 2 ( 2x + x )

30 = 6x

x = 30/6= 5

length = 10cm

b = 5cm


hope it helps uu frnd. .

Answer 2

let the measure of sides be 2x and X
Then ,
perimeter of rectangle = 2( l + b )
=> 30 = 2(2x+x)
=> 30 = 4x + 2x
=> X = 30/6
=> X = 5
sides = X = 5 cm .
2x = 2×5 = 10 cm
