Question

If the Length of a rectangle is 80 cm and perimeter is 8 m then what will be the breadth and area of it

Answer 1

Answer:

320cm

Step-by-step explanation:

length=80cm

perimeter=8m

=8×100cm

=800cm

we know that, perimeter =2(l+b)

therefore,

perimeter=800cm

2(l+b)=800cm

2(80+b)=800cm

80+b=400cm

b=400-80

b=320cm
