Question

B-124
M
If the perimeter of a rectangle is 130 cm and its breadth is 30 cm, then calculate the
area of a rectangle.​

Answer 1

perimeter=2(l+b)

130=2(l+30)

130=2l+2*30

130= 2l+60

130-60=2l

70/2= l

l= 35

so the area will be

area =l*b

=35*30

= 1050cm^2

Answer 2

Answer:

perimeter = 2×(length + breadth)

130 = 2×(l + 30)

130 = 2l + 60

70 = 2l

70/2 = l

35 cm = length

area = length×breadth

= 35×30

= 1050cm²
