Question

A thin wire 44 cm long is formed into a rectangle if the width of the rectangle is 10 cm. what is its length? also calculate area​

Answer 1

1,perimeter=sum of all sides=44cm perimeter of rectangle =2 (l+b)

44=2 (1+10)

44÷2=l+10

22=l+10

22-10=11

lenght of the rectangle = 11

2,Area of the rectangle = length × width

= 10 × 11

= 110

Area = 110
