Question

A rectangle has same area as that of a square of size 10 m. If the breadth of the rectangle is 8 m, find the perimeter of the rectangle.​

Answer 1

Answer:

12 m

Step-by-step explanation:

Perimeter of square= 4xside

=4x10m

=40m

Perimeter of rectangle=2(l+b)

40=2(l+8)

40=2l+16

40-16=2l

24=2l

24/2=l

12m=l

Answer 2

Answer:

Answer is 41m

Step-by-step explanation:

given that area of rectangle=area of square

a=10

area of square=a^2=10×10=100 msq

l×b=100.

given b=8

l×8=100

l=100/8=12.5

perimeter of rectangle=2(l+b)=2(12.5+8)=2×20.5

=41 m
