Question

The ratio of two sides of a parallelogram is 2 : 3 and its perimeter is 60 cm. Find the sides of the parallelogram

Answer 1

Step-by-step explanation:

The ratio of two sides of a parallelogram is 2 : 3 and its perimeter is 60 cm

let 2:3 be 2x & 3x...

2(l+b)=60

2(2x+3x)=60

4x+6x=60

10x=60

x=6

∆2x=2×6=10

3x=3×6=18

it takes a lot of effort to type the whole answer.....

can't u do a little effort to press thanks

Answer 2

Answer:

let the ratio of the two sides of a parallelogram be 2x and 3x

2(2x + 3x) = perimeter of parallelogram

2(2x+3x)=60

4x + 6x =60

10x = 60

x = 60÷10

x = 6

therefore,2x= 2×6=12

3x= 3×6 =18

therefore sides of the parallelogram are 12 and 18
