Question

Adjacent sides of a parallelogram are in the ratio 1:3 and their perimiter is 88 cm then find lenth of sides​

Answer 1

Answer:

Step-by-step explanation:

Let the adjacent side be 1x and 3x respectively.

We know that opposite sides of parallelogram are equal and opposite

So, 1x+3x+1x+3x=8x [Perimeter]

Given, 8x=88

x=11

Hence length of sides of parallelogram are 1x11 and 3x11 or 11 cm and 33 cm

Answer 2

ᴘᴇᴇɪᴍᴇᴛᴇʀ ᴏғ ᴘᴀʀᴀʟʟᴇʟᴏɢʀᴀᴍ = 2( ᴀ+ʙ)

ᴀ = 1 x ; ʙ = 3x

• P = 2(1x + 3x)
• 88 = 2(4x)
• 88 = 8x
• 88/11 = x
• 11 = x
