Question

A rectangle having length of a side 1 point
is 12 and length of diagonal is 20
then what is length of other side?
O (A)2
O (B) 13
O
(C) 5
O
(D) 16​

Answer 1

Answer:

(D) 16​

Step-by-step explanation:

we know that,

All angles of a rectangle are 90° .

Diagonal of rectangle = √(Length² + Breadth²)

putting given values we get,

→ Diagonal = √(Length² + Breadth²)

→ 20 = √(12² + Breadth²)

squaring both sides

→ 20² = 12² + Breadth²

→ Breadth² = 20² - 12²

→ Breadth² = 400 - 144

→ Breadth² = 256

→ Breadth² = 16²

square root both sides,

→ Breadth = 16 cm. (D) (Ans.)

Hence, length of other side will be 16 cm .

Answer 2

Complete please bhai

$\sf\small\blue{Given:-}$

• A rectangle having length of a side is 12 and length of diagonal is 20.

$\sf\small\blue{Find:-}$

• The length of other side .

$\sf\small\blue{Solution:-}$

we know that,

All angles of a rectangle are 90° .

Diagonal of rectangle = √(Length² + Breadth²)

putting given values we get,

→ Diagonal = √(Length² + Breadth²)

→ 20 = √(12² + Breadth²)

squaring both sides

→ 20² = 12² + Breadth²

→ Breadth² = 20² - 12²

→ Breadth² = 400 - 144

→ Breadth² = 256

→ Breadth² = 16²

square root both sides,

→ Breadth = 16 cm.

$\sf\small\blue{Note:-}$

• Hence, length of other side will be 16 cm .
