Rectangle Properties | MCQs

Explanation

The perimeter of a rectangle is the total distance around it.

Formula: Perimeter = 2 × (Length + Width).

Explanation

To find the area of the strip:

1. Calculate the area of the larger rectangle (including the strip):

New length = 82 + 2_4 = 90 cm

New width = 75 + 2_4 = 83 cm

Area of larger rectangle = 90 * 83 = 7470 cm²

2. Calculate the area of the original rectangle:

Area = 82 * 75 = 6150 cm²

3. Find the area of the strip:

Area of strip = Area of larger rectangle - Area of original rectangle

= 7470 - 6150

= 1320 cm²

Explanation

Width =p/2-h P=30 H=10 W=30÷2-10=5cm

w=5cm l Length 10 cm P Perimeter 30 cm Using the formula P=2(l+w) Solving forw w=P 2﹣l=30 2﹣10=5cm
