In all the questsions similar formulas are applied:

First we need to use the perimeter formula:

Perimeter = 2 ( Length + Bredth)

Then, we need to write Lenght in terms of breadth.

Then we need to find the area = Lenght x Breadth

1) Length = 7/5 Breadth

Formula: 2( L + B ) = 24

L + B = 12

7/5 B + B = 12

12 B / 5 = 12

B = 5

L = 7

Area = 35

Similarly all other questions can be done, answers of which I am giving below.

2) 243

3) 384

4) 1008

5) 360 

Please best the solution !!!!!!!11
