Question

Q.55 A rectangle is formed by 100 cm wire. Find out the maximum area of this rectangle.

Answer 1

Answer:

length of the wire= 100 cm

i.e. perimeter of the wire = 100 cm

2(l+b)=100 cm

(l+b)= 100/2 cm

(l+b) = 50 cm

for finding maximum area of the rectangle

l=b

l+l = 50cm

2l = 50cm

l = 25cm

area of the rectangle = l × b

i.e. 25cm × 25cm

= 625cm²
