Question

In the parallelogram,the altitude is twice the length of base. It's area is 450cm square. find the length of base and altitude.​

Answer 1

Answer:

Base = 15, Altitude = 30.

Step-by-step explanation:

So, area of parallelogram is  = base * altitude. So,

x * 2x = 450,

2x^2 = 450,

x^2 = 225,

x = 15.

So base = 15 and altitude = 15 * 2 = 30.

Answer 2

Answer:

Aʀᴇᴀ ᴏғ ᴘᴀʀᴀʟʟᴇʟᴏɢʀᴀᴍ=ʙᴀsᴇ×Aʟᴛɪᴛᴜᴅᴇ

Sᴏ,

x×2x=450

2x^2=450

x^2=225

x=15

Hᴇɴᴄᴇ,

Bᴀsᴇ=15

Aʟᴛɪᴛᴜᴅᴇ=15×2=30
