Answer 2

Step-by-step explanation:

$\bold \green{\underline{Given:}}$

• Perimeter of a rectangle is 180 cm.
• Breadth of a rectangle is 55 cm.

$\bold \green{\underline{To\: Find:}}$

• Length and area of rectangle.

$\bold \green{\underline{Used\: Formula:}}$

• Perimeter of rectangle = 2 (l + b)
• Area of rectangle = l × b

$\bold \green{ \underline{Solution:}}$

A.T.Q,

Perimeter of rectangle = 180 cm

2 (l + b) = 180

2 (l + 55) = 180

l + 55 = 180/2

l + 55 = 90

l = 90 - 55

l = 35 cm

Therefore, length is 35 cm.

Now

• Area of rectangle = l × b

Area = (35 × 55) cm²

Area = 1925 cm²

Therefore, area is 1925 cm².
