Question

plz answer fast it is urrgent ​

Answer 1

Answer:

Perimeter of rec. is 130 cm

Breadth of rect. is 30 cm

Now,

perimeter of rect. =2(length+breadth)

130=2(length+30 cm)

130/2=length+30cm

65

65-30=length

length of rectangle is 35 cm

So, now

Area of rectangle=length×breadth

35cm×30cm

area of rect. =1050cm

Step-by-step explanation:

Hopefully you got it!

Answer 2

Answer:

Length is 35 cm and Area is 1050 sq. cm

Step-by-step explanation:

We know that,

Perimeter of Rectangle = 2×(l+b)

Given, b = 30 and Perimeter = 130

∴, 130 = 2×(l+30)

130 = 2l + 60

2l = 70

l=35

Hence, Area of rectangle = l × b = 30 × 35 = 1050
