Answer 1

QUESTION:

A wire of length 30cm is bent to form a rectangle of length 12cm, find the breadth of rectangle.

Given:

Length of the wire=30cm

We can get:

So, perimeter of the rectangle=30cm

Length of the rectangle = 12cm

To find:

Breadth = ?

Solution:

As,

Perimeter = 2(l+b)

30 = 2 (12+B)

30 = 24 + 2B

30 - 24 = 2B

6 = 2B

B = 3

Therefore:

Breadth = 3 cm Ans

Symptoms of photosensitivity may include a pink or red skin rash with blotchy blisters, scaly patches, or raised spots on areas directly exposed to the sun. Itching and burning may occur and the rash may last for several days. In some people, the reaction to sunlight gradually becomes less with subsequent exposures.
