Question

A rod 28 cm long is to be bent to make a rectangle.
How about a rectangle of diagonal 8 cm​

Answer 1

Step-by-step explanation:

We know that all the angles of a rectangle are 90° and the diagonal divides the rectangle into two right angled triangles.

So, 48 m will be one side of the triangle and the diagonal, which is 50 m, will be the hypotenuse.

According to the Pythagoras theorem:

(Hypotenuse)2 = (Base)2 + (Perpendicular)2

Perpendicular =

√

(Hypotenuse)2-(Base)2

Perpendicular =

√

(50)2-(48)2

=

√

2500-2304

=

√

196

=14 m

∴ Other side of the rectangular plot = 14 m

Length = 48m

Breadth = 14m

∴ Area of the rectangular plot = 48 m × 14 m =
