Answer 1

Analysis

The given figure is a rectangle and we have to find the measures of its various aspects such as perimeter, area, diagonal etc.

Answers:

Question 1:

We know that the area of a rectangle is the product of its length and breadth.

Length = 4 cm

Breadth = 2 cm

Area = lb

= 4 x 2

= 8 cm²

∴ The required answer is option B.

Question 2:

As per the properties of a rectangle, the opposite sides are equal and parallel.

AB = CD where AB = 4 cm

∴ CD = 4 cm

∴ The required answer is option B.

Question 3:

We know that the perimeter of a rectangle is two times the sum of its length and breadth.

Length = 4 cm

Breadth = 2 cm

Perimeter = 2 (l +b)

= 2 x (4+2)

= 2 x 6

= 12 cm

∴ The required answer is option C,

Question 4:

As per the properties of a rectangle, the opposite sides are equal and parallel.

AD = BC where AD = 2 cm

∴ AD = 2 cm

∴ The required answer is option A.

Question 5:

The formula to find the measure of the diagonal of a rectangle is the root of the sum of the squares of the length and breadth.

Diagonal = $\sqrt{l^2+b^2}$

where l and b denotes length and breadth respectively.

= $\sqrt{4^2+2^2}$

= $\sqrt{20}$

∴ The required answer is option B.
