Question

STUDY QUESTIONS
1. (a) State what do you understand by the area of
an object.
(b) State the standard international unit of area
(c) State two multiples and two sub-multiples of
SI unit of area and express their numerical
values in SI units.
2. How can you find the length of a rectangular
body, if you know its area and breadth without
using a measuring scale?​

Answer 1

1. (a) In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure.

(b) The S. I. unit of Area is

$m^2$

(c) Multiple...

Deca..=10

hecto...=100

Sub multiples....

Deci =1/10

Centi=1/100

2. Consider that the Area (A) and Breadth (B) of the Rectangle is given.

Then for Finding the Length ,ie, "L" of the Rectangle, We should equate the length and breadth to the Area of the Rectangle

using the Formula:

A = Lx B

On Solving the above equation , we get the Length of the Rectangle.
