Answer 1

Answer:

hope it helps you

I have just taken the of formula of perimeter which is perimeter of rectangle = 2(length+breadth)

just solve such problems by linear equations in one variable

Answer 2

Let the measure of sides be 4t and 5t respectively.

perimeter=2×(l+b)

180=2×(4t+5t)

180=2×(4t+5t)180=18t

t=10

So sides are,4t=4×10=40cm

So sides are,4t=4×10=40cm5t=5×10=50cm
