Question

Q. The perimeter of a rectangle is 240 cm if the breadth of the rectangle is 30 cm find its length also find the area of rectangle​

Answer 1

${\huge{\underline{\bf{AnsWer :}}}}$

Perimeter of the rectangle = 240 cm

Breadth = 30cm

Length = ??

We know that,

Perimeter of a rectangle = 2(l + b)

=> 240 = 2(l + 30)

=> 240/2 = l + 30

=> 120 = l + 30

=> l = 120-30

=> l = 90cm.

Hence, we got length as 90cm

Area of the rectangle = l*b

= 90*30

= 2700cm² ans.

Answer 2

Step-by-step explanation:

40 is the width

therefore, b×h

=30×40=120cm³
