Question

8.
If the base and height of a parallelogram are in the ratio 7:3 and the height is 45 cm
then, find the area of the parallelogram.
​

Answer 1

Answer:

4725cm^2

Step-by-step explanation:

height = 45cm

base = 45cm/3 * 7 (as ratio of b:h = 7:3)

= 105cm

area = bh

= 45cm * 105cm

= 4725cm^2

Answer 2

Let base=7x

Height=3x

A.T.Q

3x=45

x=15

Height =3×15=45

Base=7×15=105

Area of Parallelogram =Base×Height

Area=105×45=4725cm^2 is your answer.
