Question

According to class 8 please solve

Answer 1

i) The value of x is 3.

ii) TE = 20cm

RN = 20cm

Explanation:

According to the properties of rectangles,

The diagonals of rectangles are equal and bisect each other at 90°.

As per this,

OR = OT

`2x + 4 = 3x + 1`

`4 - 1 = 3x - 2x`

`3 = x`

TE = 2OT

TE = 2(3x + 1)

= 6x + 2

= 6(3) + 2

= 18 + 2

= 20

RN = 2OR

RN = 2(2x + 4)

= 4x + 8

= 4(3) + 8

= 12 + 8

= 20
