Question

if the length of a rectangle is 50 cm and its perimeter is 140 cm find the breadth and area​

Answer 1

Step-by-step explanation:

Breadth 20cm

Area-1000cm³

As the formula of perimeter is 2*(l+b)

Answer 2

l=50cm

p= 140cm

b=?

A=?

P=2(l+b)

140=2(50+b)

140/2= 50+b

70=50+b

70-50=b

20=b

and A= l x b= 50 x 20=1000
