Question

A wire 44cm long is bent to form a square.A ribbon 44cm long is made to corm a circualr ring.Which enclosed more area and by how much

Answer 1

Perimeter of square=4a=44cm
Side=11cm.
Area=(11)^2
Area=121cm^2
Perimeter of circle=2πr=44cm
r=44x7/22x2
r=7cm
Area=πr^2
Area=154cm^2

So, Circle encloses more area than square by (154-121)=33cm^2.

Hope this will help u

Answer 2

length of wire=perimeter of squar
44=4a
a=11cm
area of square=a²=(11)² =121cm²
again,
length of ribbon=circumference of circle
44=2πr
44=2×22/7×r
r=7cm
area=πr²
=22/7×7×7
=154cm²
hence, circle enclosed more area than square by33cm²(154-121)²...... thanks
