Answer 1

$\huge\boxed{\fcolorbox{purple}{ink}{Answer}}$

Given Information:-

The area of the rectangle whose length is y and breadth is half of its length.

Need to find out:-

The area of the rectangle.

Formula used:

=> Area of rectangle = Length × Breadth

Putting the values according to the formula:

=> Area of the rectangle = y × y/2

=> Area of the rectangle = (1 × 1/2) × (y × y)

=> Area of the rectangle = 1/2y² ( square units)

Hence:-

Area of the rectangle is 1/2y² ( square units).

=> ᴀʀᴇᴀ ᴏғ ᴛʜᴇ ʀᴇᴄᴛᴀɴɢʟᴇ = /ʏ² ( sǫᴜᴀʀᴇ ᴜɴɪᴛs)

ʜᴇɴᴄᴇ:-

ᴀʀᴇᴀ ᴏғ ᴛʜᴇ ʀᴇᴄᴛᴀɴɢʟᴇ ɪs /ʏ² ( sǫᴜᴀʀᴇ ᴜɴɪᴛs).
