Question

Can anyone say the me the answer of 7 question pls

Answer 1

Answer:

P=130 cm

Formula for perimeter=2(l+b) 130=2(l+30)

130=2l+60 130-60=2l 70=2l 70/2=| 35=| Therefore l = 35cm

Answer 2

Answer:

To find:-

length of rectangle(l) = ?

breadth of rectangle (b) =30 cm

Given:-

Perimeter of rectangle = 130 cm

2(l+b) = 130

2(l+30)=130

l+30=

$\frac{130}{2}$

l+30=65

l=65-30

=35

Therefore , the lenght of the rectangle is 35 cm.

Now,

area =l*b

=35*30

=1050 cm^2

Therefore , area of the rectangle is 1050

${cm}^{2}$
