Question

the length of a rectangle is 5 cm more than its breadth if the perimeter of a rectangle is 38 cm find its area​

Answer 1

Step-by-step explanation:

b is breadth

as they said length is 5 more than of breadth so

L=5+b

perimeter is 38 so formula of perimeter of rectangle is 2(l+b)

l+b=38÷2

l+b=19

so..

5+b+b=19

5+2b=19

2b=14

b=14÷2=7

b=7

l=5+b

l=5+7

l=12

area of rectangle is l×b

so 12×7=84
