Question

The base and corresponding altitude of a parallelogram are 12 cm and 6.5 cm respectively, then its area is_sq cm.

a)80
b)79
c)78
d)77.5​

Answer 1

Answer:

Area of the parallelogram = 78 cm²

Step-by-step explanation:

Given :

Base = 12 cm

Corresponding altitude or Height = 6.5 cm

To find :

The area of the parallelogram

Taken :

To find the area of the parallelogram use this formula -:

$\boxed{\bf{A=bh}}$

Where,

A = Area of the parallelogram

b = Base

h = Height

Solution :

$:\Rightarrow\bf{A=12cm\times6.5cm}$

$:\Rightarrow\bf{A={78cm}^{2}}$

So , the area of the parallelogram is 78 cm².

Extra information :

▪︎To find the perimeter of the parallelogram -:

$\boxed{\sf{P=2(a+b)}}$

Where,

P = Perimeter of the parallelogram

a = Side

b = Base

Answer 2

C) 78 is the correct answer for the given question
