Perimeter Calculation | MCQs

Explanation

Perimeter of Rhombus  = 2 (l +b)

                                         = 2 ( 6 +6 )

                                         = 2 (12)

                                         = 24

Explanation

Given:

Perimeter = 294 m

Length = 85 m

Let's denote the width as W. The formula for the perimeter of a rectangle is:

Perimeter = 2(Length + Width)

294 = 2(85 + W)

147 = 85 + W

W = 62 m

Now, to find the area:

Area = Length * Width

= 85 * 62

= 5270 m²

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

Explanation

 Let’s find the lengths of all three sides using the distance formula:

A(0,4), B(0,0), C(3,0)

AB = √[(0−0)² + (4−0)²] = √[16] = 4

BC = √[(3−0)² + (0−0)²] = √[9] = 3

CA = √[(3−0)² + (0−4)²] = √[9 + 16] = √25 = 5

Perimeter = AB + BC + CA = 4 + 3 + 5 = 12
