Question

3) The length of a rectangle is 5 cm more than breadth. If the perimeter of the rectangle is
38 cm,find its area.​

Answer 1

Answer:

84cm

Step-by-step explanation:

perimeter formula=2(l+b)

breadth=x

length=x+5

perimeter=38cm

2(x+x+5)=38cm

2(2x+5)=38cm

4x+10=38cm

4x=28cm

x=7cm

length=x+5=7+5=12cm

breadth=x=7cm

area=l*b

      =7*12

      =84cm

Answer 2

Answer:

84 sq.m

Step-by-step explanation:

l=5+b

=>2(5+2b)

=>4b=28

=>b=7

area=l*b

      =12*7=84 sq.m
